Frosted terrian on Utopia Planitia, taken by the Viking 2 lander in 1979. Utopia Planitia (Greek and Latin: "Utopia Land Plain") is a large plain [2] within Utopia, the largest recognized impact basin on Mars [a] and in the Solar System with an estimated diameter of 3,300 km (2,100 mi). [1]
The crater depth is 7,152 m (23,465 ft) below the standard topographic datum of Mars. [1] Hellas Planitia / ˈ h ɛ l ə s p l ə ˈ n ɪ ʃ i ə / is a plain located within the huge, roughly circular impact basin Hellas [a] located in the southern hemisphere of the planet Mars. [3] Hellas is the third- or fourth-largest known impact crater in ...
A giant planet, sometimes referred to as a jovian planet (Jove being another name for the Roman god Jupiter), is a diverse type of planet much larger than Earth. Giant planets are usually primarily composed of low- boiling point materials ( volatiles ), rather than rock or other solid matter, but massive solid planets can also exist.
First directly imaged planetary body to have its spectrum taken and first planet discovered orbiting a brown dwarf. Its mass is well below the limit for deuterium fusion in brown dwarfs of 13 M J. This planet will shrink to a size slightly smaller than Jupiter as it cools over the next few billion years. PDS 70 c: 1.13 +0.56 −0.43 – 2.04 +0.61
Olympus Mons (/ ə ˌ l ɪ m p ə s ˈ m ɒ n z, oʊ-/; [4] Latin for 'Mount Olympus') is a large shield volcano on Mars.It is over 21.9 km (13.6 mi; 72,000 ft) high as measured by the Mars Orbiter Laser Altimeter (MOLA), [5] about 2.5 times the elevation of Mount Everest above sea level.
Kepler-16b is a gas giant, an exoplanet that is near the same mass and radius as the planets Jupiter and Saturn.It has a temperature of 188 K (−85 °C; −121 °F). [citation needed] The planet has a radius of 0.77 R J, slightly smaller than Saturn, and has no solid surface.
According to the IAU's explicit count, there are eight planets in the Solar System; four terrestrial planets (Mercury, Venus, Earth, and Mars) and four giant planets, which can be divided further into two gas giants (Jupiter and Saturn) and two ice giants (Uranus and Neptune). When excluding the Sun, the four giant planets account for more than ...
For the giant planets, the "radius" is defined as the distance from the center at which the atmosphere reaches 1 bar of atmospheric pressure. [ 11 ] Because Sedna and 2002 MS 4 have no known moons, directly determining their mass is impossible without sending a probe (estimated to be from 1.7x10 21 to 6.1×10 21 kg for Sedna [ 12 ] ).
