Coordinates of famous places on Mars
Obiblion · updated
Olympus Mons sits at roughly 18.7°N 133.8°W, Valles Marineris centres near 14°S 59°W, Jezero Crater is at about 18.4°N 77.6°E and Gale Crater at about 5.4°S 137.8°E. These are approximate centre points, written with north/south and east/west as on a globe.
The giants: Olympus Mons and Valles Marineris
Olympus Mons, about 18.7°N 133.8°W (226.2°E), is the largest known volcano in the Solar System. It rises roughly 22 km above the surrounding datum and spans about 600 km at its base.
Valles Marineris, centred near 14°S 59°W, is a canyon system about 4,000 km long and up to around 7 km deep. It would stretch across most of the width of the continental United States.
Where the rovers landed
Jezero Crater, about 18.4°N 77.6°E, is where NASA's Perseverance rover landed in February 2021. The crater, roughly 45 km across, once held a lake and a river delta.
Gale Crater, about 5.4°S 137.8°E, is home to the Curiosity rover, which landed in August 2012. The crater is around 150 km wide and holds a mountain of layered sediment.
Basins and highlands
Hellas Planitia, near 42.7°S 70°E, is one of the largest impact basins in the Solar System, roughly 2,300 km across and several kilometres deep.
Elysium Mons, near 24.8°N 146.9°E, is a large volcano in the Elysium region, and Argyre Planitia, around 50°S 44°W, is another large impact basin in the southern highlands.
Reading Mars coordinates
Mars maps often give longitude from 0° to 360° east, so Olympus Mons appears as 226.2°E. Obiblion shows longitude as degrees east or west of the prime meridian, so the same place reads 133.8°W. Both describe the same spot.
Every Obiblion parcel on Mars carries coordinates in that form, plus the region it belongs to, such as Tharsis Rise or Valles Expanse, so you can choose a place with a story. Values here are rounded and describe each feature's centre.
Questions
What are the coordinates of Olympus Mons?
Approximately 18.7°N 133.8°W, which is the same as 18.7°N 226.2°E on maps that use 0–360° east longitude.
Where did Perseverance land on Mars?
In Jezero Crater, at about 18.4°N 77.6°E, in February 2021.
How do Mars longitudes work?
Longitude is measured from the Martian prime meridian. Many maps use 0–360° east; others use east and west up to 180°. They are two ways of writing the same position.
Can I choose a parcel near Olympus Mons?
Obiblion's Mars parcels sit on exact coordinates in regions such as Tharsis Rise, home of Olympus Mons. You can explore the map and choose a parcel by its coordinates.
