Pluto (bottom left) compared in size to the Earth and the Moon. Pluto's diameter is 2 376.6 ± 3.2 km [5] and its mass is (1.303 ± 0.003) × 10 22 kg, 17.7% that of the Moon (0.22% that of Earth). [125] Its surface area is 1.774 443 × 10 7 km 2, or just slightly bigger than Russia or Antarctica (particularly including the Antarctic sea ice ...
The 583.92-day interval between successive close approaches of Venus to Earth is equal to 5.001444 Venusian solar days, making approximately the same face visible from Earth at each close approach. Whether this relationship arose by chance or is the result of some kind of tidal locking with Earth is unknown.
One particularly distant body is 90377 Sedna, which was discovered in November 2003.It has an extremely eccentric orbit that takes it to an aphelion of 937 AU. [2] It takes over 10,000 years to orbit, and during the next 50 years it will slowly move closer to the Sun as it comes to perihelion at a distance of 76 AU from the Sun. [3] Sedna is the largest known sednoid, a class of objects that ...

Alpha Centauri – star system nearest to the Solar System, at about 4.4 light years away; Solar System – star and planetary system where the Earth is located. Earth – the only planet known to have life.
An observer aloft in Venus's cloud tops, on the other hand, would circumnavigate the planet in about four Earth days and see a sky in which Earth and the Moon shine brightly (about magnitudes −6.6 [5] and −2.7, respectively) at opposition. The maximum angular separation between the Moon and Earth from the perspective of Venus is 0.612°, or ...
The planets are, in order of distance from the Sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. There are three main belts of minor bodies: The asteroid belt, between Mars and Jupiter. The Kuiper belt beyond Neptune, followed by the scattered disc. The Oort cloud in the boundaries of the Solar System.
The geography of Pluto refers to the study and mapping of physical features across the dwarf planet Pluto. On 14 July 2015, the New Horizons spacecraft became the first spacecraft to fly by Pluto. [ 1 ] [ 2 ] During its brief flyby, New Horizons made detailed geographical measurements and observations of Pluto and its moons .
