The distance to Capella.?

Question

if the apparent magnitude of capella is 0.06, the spectral clas is G8, the parallax is 0.073 and the absolute magnitude is -0.6, what would the distance be and do you work it out?

Answer 1

p = 0.073"

So the distance

1/0.073 = 13.7 parsecs

=13.7 X 3.26 LY/pc = 44.66 Light Years

Answer 2

more than a mile,

and i worked it out by common sence.

Answer 3

you have enuf data to work it out two ways: either by parallax, or by magnitudes. the answers should agree. :-)

the fact that the absolute magnitude is only slightly brighter than the apparent magnitude should give you a rough idea of the distance with no calculation at all.

Answer 4

about 44 light years
