Eris is a trans-Neptunium object (TNO) and a member of a high-eccentricity population known as the scattered disk. It has one known moon, Dysnomia. As of February 2016, its distance from the Sun was 96.3 astronomical units (1.441×1010 km; 8.95×109 mi), roughly three times that of ...
Eris is still smaller than theEarth’sMoon, having about two thirds of the Moon’s diameter and one third of its volume. Eris is not always the most distant dwarf planet. At Eris’ furthest point from the Sun (Aphelion) it is so distant it is outside the Kuiper Belt, however at its ...
Pluto orbits at an average of about 39 times Earth's distance from the sun. Dysnomia, named after the mythological daughter of Eris, is about 440 miles (700 km) in diameter and composed mostly of ice. "Just like the Earth-moon system, tides on Eris slowly push Dysnomia ...
Eris' distance allowed astronomers to makeprecise measurementswhen the dwarf planet passed in front of a dim star in 2010, in an event known as an occultation. In addition to measuring Eris’ size, researchers were also able to determine its shape, size and mass. The observations helped scient...
An object has an average distance of 920000000 km from Sun. What is its orbital period (in years)? What is the average orbital velocity of the Earth? How many astronomical units away from Earth is the Oort cloud? What is the angular diameter of Saturn (in degrees) as seen from the ...
What is the perihelion distance of Eris? What is the temperature of Alpha Centauri? What is Eris made of? How far is Eris from Earth? How long is a year on Eris? What temperature is the Oort cloud? What is the temperature range on Mercury? What is the temperature of the sun in cels...
sun. Pluto is much smaller than Mercury, and only two-thirds the size of Earth's moon. Its orbit is tilted and eccentric, crossing Neptune's. No other planet acted like this. In 2000, astronomers found other objects orbiting the sun in the deep outer solar system, with qualities very ...
KBOs orbit at a mean distance from the Sun larger than the mean orbital distance of Neptune (about 30 astronomical units [AU]; 4.5 billion km [2.8 billion miles]). The outer edge of the Kuiper belt is more poorly defined but nominally excludes objects that never go closer to the Sun tha...
