Eris is far less than a light year away. Eris varies in distance between 99 and 37 astronomical units away, which works out to 0.00059 and .00156 light years.
A light year is a unit of space, not time. It is the distance light travels in a year. Eris is far less than a light year away.
It takes Eris 557 years to orbit the sun
Eris varies in distance from the sun between about 38 and 98 AU, which works out to 0.0006 and 0.0015 light years. In other words, much less than a light year.
The Sun!
Eris orbital period is around 557 years.
Eris is in orbit around the sun. It will remain so unless perturbed from its orbit.
The time Eris takes to orbit the Sun is about 557 years.The length of Eris's orbit around the Sun is about 60 billion kilometers
it is around - 400
The dwarf planet Eris probably has no atmosphere to speak of. Eris orbits beyond Neptune, in the bitter cold distances from the Sun; most gasses would condense and freeze, and the tenuous vapors that might remain would be too light to be bound by Eris' weak gravity.
No, planets don't bounce. Eris travels in an oval shaped orbit around the sun.
It is estimated a Eris day is 26 Earth hoursA year on Eris is estimated to be 557 Earth Years
