Solution
The correct option is B Moon
Explanation:
- The nearest nebula to earth is the Helix Nebula. It is 700 light-years away from Earth.
- The Moon is about 1.25 Light Seconds away from the Earth as the reflected sunlight from the Moon takes about 1.25 seconds to reach the Earth or in terms of light-years 3.96 x 10−8 Light Years.
- It takes 8.3 minutes for light to travel from the Sun to the Earth (a distance of 1.58 × 10-5 light-years).
- 'The Unicorn' lies 1,500 light-years from us and is just three times more massive than the sun. It is the closest known black hole to Earth, a weirdly tiny object dubbed "The Unicorn" that lurks just 1,500 light-years from us.
