If the message is sent by radio, then it takes 6 years to reach you.
If by USPS, then somewhat longer.
Traveling at the speed of light, it would take a spacecraft 40 years to reach a star located 40 lightyears away from Earth.
It would all depend on the speed travelling, as time = distance/speed.
over 9000 lightyears away
2 lightyears
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.
1 mile unless you go the long route voa heaven and the it is 10000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 lightyears away
At a speed of 1,516 miles per hour, it will take you 1,902,141 years to travel 4.3 light-years.
72 1/2 lightyears
The Canis Major Dwarf galaxy has already collided with the Milky Way, and is currently located inside our galaxy, approximately 42,000 lightyears away from our galactic center. It is located 25,00 light years from our solar system, which puts us closer to it rather than the center of our galaxy, which is 30,00 lightyears away. Hope this answered your question!
furlongs, miles, kilometres, lightyears etc.
One light year is around 10 trillion km or 6 trillion miles. Nine lightyears would be 90 trillion km or 54 trillion miles. You would generally just say nine lightyears though.
Mercury Is 0.000131 lightyears away from earth
