For example, if a TNO is incorrectly assumed to have a mass of 3.59 × 10 20 kg based on a radius of 350 km with a density of 2 g/cm 3 but is later discovered to have a radius of only 175 km with a density of 0.5 g/cm 3, its true mass would be only 1.12 × 10 19 kg.
Kepler-37e is listed with a radius of 0.37 ± 0.18 R 🜨 in the Exoplanet Archive based on KOI data, but the existence of this planet is doubtful, [22] and assuming its existence, a 2023 study found a mass of 8.1 ± 1.7 M 🜨, inconsistent with such a small radius.
The sizes are listed in units of Jupiter radii (R J, 71 492 km).This list is designed to include all planets that are larger than 1.6 times the size of Jupiter.Some well-known planets that are smaller than 1.6 R J (17.93 R 🜨 or 114 387.2 km) have been included for the sake of comparison.
Universe Sandbox is a series of interactive space sandbox gravity simulator educational software video games.Using Universe Sandbox, users can see the effects of gravity on objects in the universe and run scale simulations of the Solar System, various galaxies or other simulations, while at the same time interacting and maintaining control over gravity, time, and other objects in the universe ...
This template is to show size comparison of Jupiter, Neptune and the Earth alongside extrasolar planets that have their radial size confirmed. {{ Planetary radius | radius = <!--simplified number of the radius (Jupiter equals 100px)--> }}
As of 2018, beta testing builds of version 1.7.0 are available, [16] [17] as well as the bugfix releases 1.6.2 [18] and 1.6.3, [19] which were released in 2020 and 2023 respectively. Celestia was ported to mobile devices in 2020, and it continues to receive updates and experimental beta versions.
The Moon, Io and Earth shown to scale. Although significantly smaller, some of the Solar System's moons and dwarf planets share similarities to Earth's density and temperature. The index can be calculated for objects other than planets, including natural satellites, dwarf planets and asteroids. The lower average density and temperature of these ...
Size comparison of Kepler-10c, with Earth and Neptune A mega-Earth is a proposed neologism for a massive terrestrial exoplanet that is at least ten times the mass of Earth . Mega-Earths would be substantially more massive than super-Earths (terrestrial and ocean planets with masses around 5–10 Earths).
