Answer:
The Correct Answer would be Light Year. Light Year is a unit to measure distance from any planet, be it earth or any other, to any other planet, star or galaxy in space. 1 Light Year = 9.5 trillion km = 9.5×10¹² km.
Explanation:
Light travels at a speed of 3×10⁸ meters per sec in empty space. The speed of light is basically used to measure how far away things are in space. A light-year is the distance that light can travel in one year ( 12 months or we can say 365 days). In one year, light travels about 9,460,000,000,000 kilometers or lumsum 9.5×10¹² km. This distance is basically known as 1 light-year. For example, the nearest star to Earth is about 4.3 light-years away. The Milky Way is about 1.5×10⁵ light-years across, and the nearest galaxy, Andromeda, is about 2.3 million light-years away from us.
