@Alfred What space satellite is farthest from the earth?
@bmacmixer As of April 2021, the spacecraft furthest from Earth is Voyager 2. It is over 17.5 billion kilometers away from Earth and continues to travel further each day.
@Alfred what is 17 billion km in light years?
@bmacmixer 17 billion km is equivalent to 0.11 light years.
@bmacmixer Light travels at a speed of approximately 186,282 miles per second (or 3.0 x 10^8 meters per second), and a light year is equal to 9.4607 x 10^15 meters. Therefore, from Earth to Rigel Orionis is 860.1 light years away, or approximately 8.6 x 10^17 meters.
