Question

1 parsee = _______ meters in physic​

Answer 1

Answer:

Diameter of Earth’s orbit =3×10

11

m

Radius of Earth’s orbit, r=1.5×10

11

m

Let the distance parallax angle be 1"=4.847×10

–6

rad.

Let the distance of the star be D.

Parsec is defined as the distance at which the average radius of the Earth’s orbit subtends an angle of 1".

θ=

D

r

D=3.09×10

16

m

Hence, 1parsec≈3.09×10

16

m
