What is the weight of Eris?
As Eris orbits the Sun, it completes one rotation every 25.9 hours, making its day length similar to Earth’s. However, other sources disagree on the rotation period….Eris (dwarf planet)

Is Eris heavier than Pluto?
Watching Eris That makes it slightly smaller than Pluto. Newer studies show that Eris likely is a spherical body. And, by studying the motion of Eris’ moon, Dysnomia (which was also discovered in 2005), they estimate the dwarf planet is about 27% heavier than Pluto, which means it’s denser than Pluto as well.
What is the mass of the planet Eris?
The mass of Eris from these orbital parameters is 1.67 x 10(22) +/- 0.02 x 10(22) kilograms, or 1.27 +/- 0.02 that of Pluto.
Why is Eris more massive than Pluto?
Pluto’s own elliptical orbit takes it as far away as 50 astronomical units from the sun during its 250-year revolution. This means that Eris is sometimes much closer to Earth than Pluto, although never closer than Neptune.
Could we live on Eris?
The surface of Eris is extremely cold, so it seems unlikely that life could exist there.
How cold is Eris?
It takes 557 Earth years for Eris to make one orbit around the Sun. It has a highly eccentric orbit around the Sun, which causes its surface temperature to vary from -217 degrees Celsius to -243 degrees Celsius.
What is the 11th planet from the Sun?
Eleventh planet (of the Solar System) may refer to Vesta, the eleventh object to be named a planet, later to be reclassified as an asteroid, or to Uranus, the eleventh planet from the Sun upon Vesta’s discovery, though this was quickly superseded by new discoveries.
Is Pluto more massive than the Moon?
Pluto is smaller than Earth’s moon. Its largest moon is named Charon (KAIR-ən). Charon is about half the size of Pluto. Pluto’s four other moons are named Kerberos, Styx, Nix and Hydra.
Are there 10 planets?
The order of the planets in the solar system, starting nearest the sun and working outward is the following: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then the possible Planet Nine.
