This is calculated using the following formula.

z = c * t

Where,

z is the distance to the object.

c is the speed of light.

t is the time light takes to reach Earth.

Z = 300000 km x 5.5 Hours

5.5 hours = 5.5 * 60 * 60

5.5 hours = 19800 secs

z = 300000 * 19800

z = 5940 000 000

z = 5.9 Billion km
