The four main mountain ranges of Venus are named Akna Montes, Danu Montes, Freyja Montes, and Maxwell Montes. These are found on Ishtar Terra. Mountain ranges are formed by the folding and buckling of a planet's crust. The mountain ranges of Venus, like those of the Earth, are characterized by many parallel folds and faults.
The solar system's tallest mountain is possibly the Olympus Mons on Mars with an altitude of 21.9 to 26 km. The central peak of Rheasilvia on the asteroid Vesta is also a candidate to be the tallest, with an estimated at up to between 20 and 25 km from peak to base.
Beethoven has only one, subdued massif-like rim 625 kilometres (388 mi) in diameter, but displays an impressive, well lineated ejecta blanket that extends as far as 500 kilometres (311 mi). As at Tolstoj, Beethoven ejecta is asymmetric. The Caloris basin is defined by a ring of mountains 1,300 kilometres (808 mi) in diameter.
The origin of the Lakshmi Planum and the mountain belts such as Maxwell Montes is controversial. One theory suggests they formed over a hot plume of material rising from Venus's interior, while another says the region is being compressed (pushed together) from all sides, resulting in material descending into the planet's interior.

The equatorial ridge is the tallest mountain feature on Saturn's moon Iapetus. It is 20 km (12 mi) high, and is the third tallest mountain structure in the Solar System. It runs along most of Iapetus' equator. It was discovered by the Cassini probe in 2004. The ridge's origin is unknown.
Topographic radar image view of Venus, with Ishtar Terra near center. Ishtar Terra / ˈ ɪ ʃ t ɑːr ˈ t ɛr ə / [1] is the second largest of the three continental terrae regions on the planet Venus, the others being Aphrodite Terra and Lada Terra. It is a highland region named after the Akkadian goddess Ishtar, [2] and is found in the north ...
Mons / ˈ m ɒ n z / [2] (plural: montes / ˈ m ɒ n t iː z /, [2] from the Latin word for "mountain") is a mountain on a celestial body. The term is used in planetary nomenclature : it is a part of the international names of such features.
Located near the equator of Venus, Aphrodite Terra has an area about half the size of Africa, and is much larger than the rougher Ishtar Terra. It is covered with deep rift valleys. [5] Like Ishtar Terra, Aphrodite Terra also has mountain ranges but they are only about half the size of the mountains on Ishtar. [citation needed]
