Top 10 Tallest Mountains of our Solar System

Of course, when you think about the tallest mountains, you will probably first remember the 29,000 feet (8,848 m) high Mount Everest; if you think Mount Everest is the tallest, you should read this article.

In the list of the Tallest mountains of our solar system, Mount Everest comes down very low. When Mount Everest is compared with the giant’s mountains of our solar system, it looks just like a peewee, and it could not even make it place in the list of the tallest mountain peak of the solar system, so let’s begin our journey in search of the Top 10 tallest mountains of the Solar System.

Here are the Top 10 Tallest Mountains of our Solar System

10. Euboea Montes

Euboea Montes

Location: Io (Jupiter’s’s moon)

Height: 10.5 Km, Ranges between 10.2 Km to 13.4 km (6.4 to 8.3 mi)

Origin: Tectonic

Euboea Montes is a mountain located on Jupiter’s moon Io, about 40 kilometers east of Creidne Patera caldera at coordinates 48.89 ° S 338.77 ° W. Its shape resembles a rugby ball with an area of ​​175 km up to 240 km. It was formed by tilting of a crustal block, with subsequent modification by a colossal landslide.

A curved ridge crest divides Euboeia Montes into two sections: the steep, a southern edge with an uneven surface of steep, rounded mounds, and the smoother, northern flank sloping about 6 ° to the northwest. The base on the north flake is a thick, raised deposit with round margins.

9. Limb Mountain

Limb Mountain (Oberon Moon)

Location: Oberon (Moon of Uranus)

Height: 11 km (7 mi)

Origin: Impact

Oberon was discovered on January 11, 1787, by William Herschel. It is the second-largest moon of Uranus and the ninth-largest in the solar system. A peak with a height of about 11 km was observed in some of the Wieger images near Oberon’s southeastern limb, which may be the central peak of a large impact basin with a diameter of about 375 km. A system of valleys intersects the surface of the Oberon. The mountain was probably formed as a result of asteroid and comet impact. 


8. Arsia Mons

Arsia Mons

Location: Mars

Height: 11.7 km (7.3 mi)

Origin: Volcanic

Arsia Mons is the southernmost of three volcanos on the Tharsis bulge near the planet Mars’s equator. Arsia Mons is 270 miles (approximately 435 kilometers) in diameter, and almost 12 miles high (more than 9 kilometers (5.6 mi) higher than the surrounding plains), and the summit caldera is 72 miles (approximately 110 km) wide.

The caldera of Arsia Mons was formed when the mountain collapsed in on itself after its reservoir of magma was exhausted. The caldera floor formed around 150 Mya ago.

It experiences atmospheric pressure lower than 107 pascals at the summit. Arsia Mons has 30 times the volume of Mauna Loa in Hawaii, the largest volcano on the Earth. Recent work provides evidence for glaciers on Arsia Mons at both high and low elevations. As of 2007, seven putative cave entrances have been identified in satellite imagery of the flanks of Arsia Mons.


7. Elysium Mons

Elysium Mons

Location: Mars

Height: 12.6 km (7.8 mi)

Origin: Volcanic

Elysium Mons was discovered in 1972 in images returned by the Mariner 9 orbiter. It is located on Mars in the volcanic province of Elysium, at 25.02 ° N 147.21 ° E, in the Martian Eastern Hemisphere. It is about 12.6 km (41,000 ft) above its base and about 14.1 km (46,000 ft) above the Martian datum, the third-highest Martian mountain in terms of relief fourth highest in elevation. Its diameter is approximately 240 km (150 mi), with the summit caldera about 14 km (8.7 mi).


6. Ionian Mons East Ridge

Ionian Mons East Ridge

Location: Io (Jupiter’s’s moon)

Height: 12.7 km (7.9 mi)

Origin: Techtonic

The second tallest mountain in the satellite Uranus Io is a curved double ridge and a typical canonical form. It is located at coordinates of 8.61°N 236.56°W. ( So far, we have received so much information about this mountain).

5. Ascraeus Mons

Ascraeus Mons

Location: Mars

Height: 14.9 km (9.3 mi)

Origin: Volcanic

Ascraeus Mons is a massive shield volcano located in the Tharsis region of the planet Mars and was discovered by the Mariner 9 spacecraft in 1971. It is the northernmost and tallest of three shield volcanoes collectively known as the Tharsis Montes.

Ascraeus Lacus had been named after Ascra, the rural birthplace of Hesiod; in Greek, the word “Ascraeus” is a poetic metonym for “rural.” The volcano’s name officially became Ascraeus Mons in 1973. The volcano was initially called North Spot because it was the northernmost of only four spots visible on the surface due to a global dust storm that was then enshrouding the planet.


4. Boösaule Montes

Boösaule Montes

Location: Io (Jupiter’s’s moon)

Height: 17.5 to 18.2 km (10.9 to 11.3 mi)

Origin: Tectonic

South Boösaule Mons, the highest mountain of Jupiter’s moon Io, is one of the tallest mountains in the Solar System. It is located just northwest of the volcano Pele in the Boösaule Montes. The official name of the mountain range was given in honor of Egypt’s cave, where Io gave birth to Epaphus and approved by the IAU in 1985.

South Boösaule has a relative height of 18.2 km (17.5 km from the foot), dimensions of 145 × 159 km (the diameter of the mountain range is 540 km), and it covers an area of 17,900 km2.

On the south-east side of the mountain, there is a cliff of 40 degrees, and up to 15 km high, scientists think that it was the site of a massive landslide. These structures average 6 km (4 mi) in height and reach 17.5 ± 1.5 km (10.9 ± one mi) at South Boösaule Montes. Mountains often appear as large (the average mountain is 157 km (98 mi) long), isolated structures with no apparent global tectonic patterns outlined, in contrast to the situation on Earth.


3. Equatorial Ridge

Equatorial Ridge

Location: Lapetus (Saturn’s’s moon)

Height: 20 km (12 mi)

Origin: Uncertain

Discovered by the Cassini spacecraft on December 31, 2004, Iapetus is the third-largest natural satellite of Saturn. This heavily cratered ridge has a history that is still debated upon. Iapetus is named after the Titan Iapetus, suggested by John Herschel that thought all of Saturn’s moons should be named after the Titans.

The equatorial ridge runs along the equator, and it is about 1,300 km long, 20 km wide, and 13 km high. Some peaks in the elevation rise more than 20 km above the surrounding plains, making them some of the tallest mountains of our Solar System.

It is not clear how the ridge formed. There are several theories on the ridge’s formation: a previous ring system could cause it; it might have occurred due to an ancient convective turn; it could be composed of icy material pushed up from underneath, or it could be a result from when the moon was spinning more rapidly when it was younger.


2. Olympus Mons

Olympus Mons

Location: Mars

Height: 21.9 km (14 mi)

Origin: Volcanic

Olympus Mons is twice as tall as Earth’s Mount Everest. Olympus Mons is a massive shield volcano on the planet Mars. It has a height of nearly 22 km (14 mi). It is one of the largest volcanoes, the tallest mountain of mars, and the second-highest mountain in the Solar System.

The volcano is located in Mars’s western hemisphere at approximately 18.65°N 226.2°E, just off the Tharsis bulge’s northwestern edge. The west portion of the volcano lies in the Amazonis quadrangle (MC-8) and the central and eastern parts in the adjoining Tharsis quadrangle (MC-9).

Olympus Mons results from many highly fluid, basaltic lava flow poured from volcanic vents over a long period. The size of a volcano’s caldera reflects the size of the underlying magma chamber, and Olympus Mons” caldera has a depth of about 20 miles. Olympus Mons covers an area the size of Arizona or about 114,000 square miles.

For 40 years, following its discovery in 1971, it was the tallest mountain known in the Solar System. However, in 2011, the central peak of the crater Rheasilvia on the asteroid and protoplanet Vesta was found to be of comparable height. Due to limitations in the data and the definition problem described below, it is difficult to determine which of the two is taller.


1. Rheasilvia Central Peak

Tallest mountains of our solar system

Location: Asteroid Vesta

Height: 22 km (14 mi)

Origin: Impact

Rheasilvia was discovered in Hubble Space Telescope images in 1997 but was not named until the arrival of the Dawn spacecraft in 2011. It is named after Rhea Silvia, a mythological vestal virgin and mother of Rome, Romulus, and Remus’s founders.

It is 505 km (314 mi) in diameter, which is 90% the diameter of Vesta itself, and at 75°S latitude, covers most of the southern hemisphere. The peak in the center of the crater rises 22.5 km (14.0 mi) from its base, making it the highest mountain peak in the solar system.

Vesta has a series of troughs in an equatorial region concentric to Rheasilvia. These are thought to be large-scale fractures resulting from the impact. The largest is Divalia Fossa, approx. 22 km (14 mi) wide and 465 km (289 mi) long.


So these are the tallest mountain in the solar system.

Mars and satellite of Jupiter Io have the most massive mountains in the Solar System, the hills of Mars are all volcanic, and tectonic plates form the Mountains of Io; as most people know, Olympus Mons is the tallest mountain in the Solar System, and this is true because Rheasilvia, the tallest mountain in the Solar System, is on an asteroid, and how long an asteroid will remain in any solar system is difficult to tell.

Still, No one can doubt on the stability of a planet like Mars, on which we are planning to go on, and it is not that this list will always be the same; more names will be added to it, as humans have yet not known about the entire solar system. So we have to continue our discovery in search of more tallest mountains if they do exist.
