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 ...
Neptune is the eighth and farthest known planet from the Sun. It is the fourth-largest planet in the Solar System by diameter, the third-most-massive planet, and the densest giant planet. It is 17 times the mass of Earth. Compared to its fellow ice giant Uranus, Neptune is slightly more massive, but denser and smaller.
The object was nicknamed "FarFarOut" for its distant location from the Sun, and particularly because it was even farther than the previous farthest known object 2018 VG 18 which was nicknamed "Farout". [3] It is officially known by the provisional designation 2018 AG 37 given by the Minor Planet Center when the discovery was announced. [1]
This is a list of Solar System objects by greatest aphelion or the greatest distance from the Sun that the orbit could take it if the Sun and object were the only objects in the universe. It is implied that the object is orbiting the Sun in a two-body solution without the influence of the planets, passing stars, or the galaxy. The aphelion can ...
[21] [69] This planet would be perhaps six times as massive as Earth. [70] It would have a highly eccentric orbit, and its average distance from the Sun would be about 15 times that of Neptune (which orbits at an average distance of 30.1 astronomical units (4.50 × 10 9 km)). Accordingly, its orbital period would be approximately 7,000 to ...
According to National Geographic, Earth is tilted approximately 23.5 degrees on its axis, which is the farthest point the planet is from the sun. Basically, ...
The following is a list of Solar System objects by orbit, ordered by increasing distance from the Sun. Most named objects in this list have a diameter of 500 km or more. The Sun, a spectral class G2V main-sequence star; The inner Solar System and the terrestrial planets. 2021 PH27; Mercury. Mercury-crossing minor planets; Venus. Venus-crossing ...
The order of the planets was conjecture until Kepler determined the distances from the Sun of the five known planets that were not Earth. It had been conjectured that the fixed stars were much farther away than the planets. Moon: Moon of a planet 3rd century BC 20 Earth radii (very inaccurate, true=64 Earth radii)
