The formula M = m - 5 log(d/10) gives the distance d (in parsecs) from Earth to a star with apparent magnitude m and absolute magnitude M. The star Rasalhague has an apparent magnitude of 2.08 and an absolute magnitude of 1.3. Find the distance from Earth to Rasalhague.

Step 1
We have the formula: $M = m - 5 \log_{10}(d)$, where $M$ is the absolute magnitude, $m$ is the apparent magnitude, and $d$ is the distance in parsecs. Show more…

The formula M=m-5 log (d/10) gives the distance (in parsecs) from Earth to a star with apparent magnitude and absolute magnitude . The star Rasalhague has an apparent magnitude of 2.8 and an absolute magnitude of 1.3. Find the distance from Earth to Rasalhague.

Astronomers use the distance modulus function M(r) = 5 log r - 5, where M is the distance modulus and r is the distance of a star from Earth in parsecs. (One parsec is approximately 1.92 x 10^13 miles, or approximately 20 trillion miles.) Use this function to answer the question below. Round to the nearest tenth. The distance modulus of "Star Alpha" is -1.41. How many parsecs from Earth is this star?
