Olympus Mons is partially surrounded by a region of distinctive grooved or corrugated terrain known as the Olympus Mons aureole. The aureole consists of several large lobes. Northwest of the volcano, the aureole extends a distance of up to 750 km (470 mi) and is known as Lycus Sulci ( 24°36′N 219°00′E / 24.600°N 219.000°E ...
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.
Olympus Mons, the tallest known mountain in the Solar System, is located about 1,200 km (750 mi) northwest of the Tharsis Montes, at the edge of the Tharsis region. The Tharsis Montes were discovered by the Mariner 9 spacecraft in 1971. They were among the few surface features visible as the spacecraft entered orbit during a global dust storm.
Olympus Mons and its associated lava flows and aureole deposits form another distinct subprovince of the Tharsis region. This subregion is about 1,600 kilometres (990 mi) across. It lies off the main topographic bulge, but is related to the volcanic processes that formed Tharsis. [10] Olympus Mons is the youngest of the large Tharsis volcanoes.
The main part of Tamu's rounded dome extends over an area of 450 km × 650 km (280 mi × 400 mi), totaling more than 292,500 km 2 (112,900 sq mi), many times larger than Mauna Loa, which has an area of 5,000 km 2 (1,900 sq mi), and about half the area of the Martian volcano Olympus Mons. [a] The entire mass of Tamu consists of basalt.
The submerged mountain is about 200 meters taller from base to peak than Mount Olympus, and roughly four times the size of the tallest building in the world (Dubai’s Burj Khalifa), according to ...
It is marked by the formation of extensive lava plains. The formation of Olympus Mons probably began during this period. [14] Catastrophic releases of water carved out extensive outflow channels around Chryse Planitia and elsewhere. Ephemeral lakes or seas may have formed in the northern lowlands.
Tharsis is a land of great volcanoes. Olympus Mons is the tallest known volcano in the Solar System; it is 100 times larger than any volcano on Earth. Ascraeus Mons and Pavonis Mons are at least 200 miles across and are over six miles above the plateau that they sit on—and, the plateau is three to four miles above the zero altitude of Mars. [4]
