Comparison of the sizes of planets Kepler-69c, Kepler-62e, Kepler-62f, and the Earth. All planets except the Earth are artists' conceptions. The classification of exoplanets is difficult in that many methods of exoplanet detection leave several features unknown.
These lists contain the Sun, the planets, dwarf planets, many of the larger small Solar System bodies (which includes the asteroids), all named natural satellites, and a number of smaller objects of historical or scientific interest, such as comets and near-Earth objects.
The core is surrounded by a silicate mantle that formed many of the tectonic and volcanic features on the planet. The average thickness of the planet's crust is about 50 km, and it is no thicker than 125 kilometres (78 mi), [33] which is much thicker than Earth's crust which varies between 5 kilometres (3 mi) and 70 kilometres (43 mi). As a ...
Original – Solar system planets size comparison. Largest to smallest are pictured left to right, top to bottom: Jupiter, Saturn, Uranus, Neptune, Earth, Venus, Mars, Mercury. Reason Though not of the minimum size required, but highly encyclopaedic illustrating the sizes of the planets with good quality Articles in which this image appears
This is a directory of lists of geological features on planets excepting Earth, moons and asteroids ordered by increasing distance from the Sun. Mercury
The distance separating the planet and its star is just 7% of the distance between Earth and the Sun, and the planet receives 1.6 times more energy from its star than Earth does from the Sun.
A terrestrial planet, tellurian planet, telluric planet, or rocky planet, is a planet that is composed primarily of silicate, rocks or metals. Within the Solar System , the terrestrial planets accepted by the IAU are the inner planets closest to the Sun : Mercury , Venus , Earth and Mars .
Disintegrating planet, radius is just an estimate. [7] PSR B1257+12 b (Draugr) ~0.338: Least massive known exoplanet, at 0.02 Earth masses. Radius estimated from mass-radius relationship. [8] Kepler-1520b: ≲0.36: Disintegrating planets with poorly known radii, all thought to be smaller than Mercury. [9] [10] KOI-2700b: K2-22b: Mercury: 0.3826 ...
