Question

How many parsecs is the sun from earth?

Answer 1

Distance from the Sun to the Earth in Parsecs = 4.84 x `10^-6` Parsecs.

Explanation:

Parsecs are not usually used for such small distances.

As,

1 Parsec = 3.26 Light-Years.

Parsecs should only be used for distances above 3.26 Light-years.

Sun is 8.3 Light-minutes away from the Earth.

8.3 light-minutes = 1.579 x `10^-5` light-years.

As,

3.26 Light-years = 1 Parsec

1 Light-Year = 0.306 Parsecs

1.579 x `10^-5` Light-years = 1.579 x `10^-5` x 0.306

so,

Distance from the Sun to the Earth in Parsecs = 4.84 x `10^-6` Parsecs.
