The distance from the earth to Eris depends on whether they are both on the same side of the sun or opposite sides. It will take between 346000 and 353000 hours. This is equivalent to between 39 and 40 years.
560 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.
Depending on where Eris is in its orbit, it can take anywhere from 16-29 years to get to Eris from Earth.
The average distance from the earth to the moon is approx 250000 miles. If you could travel to the moon at 25000 in a staright line, it would take 10 hours.
1. Eris is quite small. 2. Eris is very far away!
It takes Eris 557 years to orbit the sun
Eris takes approximately 550 Earth years to rotate on its axis.
About 9 years
203,830 days.
it takes 7 years for Eris to orbit 1 rotaion
The word is "revolve" or "orbit", not "rotate". It takes Eris 560 years to orbit the Sun once.
For a start, with current technology it would take a long, long time.
