Currently most of the objects of mass between 10 9 kg to 10 12 kg (less than 1000 teragrams (Tg)) listed here are near-Earth asteroids (NEAs). The Aten asteroid 1994 WR12 has less mass than the Great Pyramid of Giza, 5.9 × 10 9 kg. For more about very small objects in the Solar System, see meteoroid, micrometeoroid, cosmic dust, and ...
The next largest TNO moon is Orcus' moon Vanth at 442.5 ± 10.2 km and a poorly constrained (87 ± 8) × 10 18 kg, with an albedo of about 8%. Ceres, generally accepted as a dwarf planet, is added for comparison. Also added for comparison is Triton, which is thought to have been a dwarf planet in the Kuiper belt before it was captured by Neptune.
Olympus Mons ( / əˌlɪmpəs ˈmɒnz, 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. It is Mars's tallest volcano, its tallest planetary mountain ...
Radius is in the range of 1.2 – 120 km. [3] Disintegrating planetesimal, likely one of several orbiting its star. Likely about one-tenth the mass of Ceres and ~200 km in radius. [5] Smallest known exoplanet. [6] [7] Least massive known exoplanet, at 0.02 Earth masses. Radius estimated from mass-radius relationship. [8]
Jupiter is the biggest planet in our solar system, according to NASA. The planet is what’s known as a gas giant, which means it doesn’t have a solid surface — though it may have a solid core ...
A size comparison of Neptune and Earth. Neptune's mass of 1.0243 × 10 26 kg [7] is intermediate between Earth and the larger gas giants: it is 17 times that of Earth but just 1/19th that of Jupiter. [h] Its gravity at 1 bar is 11.15 m/s 2, 1.14 times the surface gravity of Earth, [70] and surpassed only by Jupiter. [71]
At the time Makemake and Haumea were named, it was thought that trans-Neptunian objects (TNOs) with icy cores would require a diameter of only about 400 km (250 mi), or 3% the size of Earth – the size of the moons Mimas, the smallest moon that is round, and Proteus, the largest that is not – to relax into gravitational equilibrium. [65]
The sizes are listed in units of Jupiter radii (71,492 km). All planets listed are larger than 1.7 times the size of the largest planet in the Solar System, Jupiter. Some planets that are smaller than 1.7 R J have been included for the sake of comparison.
