Size comparison of Earth and Uranus. Uranus's mass is roughly 14.5 times that of Earth, making it the least massive of the giant planets. Its diameter is slightly larger than Neptune's at roughly four times that of Earth. A resulting density of 1.27 g/cm 3 makes Uranus the second least dense planet, after Saturn.
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 outer planets Jupiter, Saturn, Uranus and Neptune, compared to the inner planets Earth, Venus, Mars, and Mercury at the bottom right The four outer planets, called giant planets or Jovian planets, collectively make up 99% of the mass known to orbit the Sun. [g] All four giant planets have multiple moons and a ring system, although only ...
The atmosphere of Uranus is composed primarily of hydrogen and helium. At depth it is significantly enriched in volatiles (dubbed "ices") such as water, ammonia and methane. The opposite is true for the upper atmosphere, which contains very few gases heavier than hydrogen and helium due to its low temperature.
List of planet types. From top to bottom: Mercury, Venus without its atmosphere, Earth and the Moon, Mars, Jupiter, Saturn, Uranus, and Neptune (not to scale) The following is a list of planet types by their mass, orbit, physical and chemical composition, or by another classification. The IAU defines that a planet in the Solar System must orbit ...
Illustration of the inferred size of the super-Earth CoRoT-7b (center) in comparison with Earth and Neptune A Super-Earth is a type of exoplanet with a mass higher than Earth 's, but substantially below those of the Solar System's ice giants , Uranus and Neptune , which are 14.5 and 17 times Earth's, respectively.

It has been noted that ESI fails to differentiate between Earth similarity and Venus similarity, where planets with a lower ESI have a greater chance at habitability. Planets with an Earth-like size Comparison of the sizes of planets Kepler-69c, Kepler-62e, Kepler-62f, and the Earth. All planets except the Earth are artists' conceptions.
The four terrestrial planets of the Solar System : Mercury and Venus. Earth and Mars. Not shown to scale. A terrestrial 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 ...
