Find the distance in parsecs to Bernard's Star, which has an annual parallax of 0.549 arcsec.
Question
Find the distance in parsecs to Bernard's Star, which has an annual parallax of 0.549 arcsec.
Solution
To find the distance to Bernard's Star in parsecs, we can use the formula for parallax:
d = 1/p
where:
- d is the distance in parsecs
- p is the parallax in arcseconds
Given that the parallax p = 0.549 arcsec, we can substitute this into the formula:
d = 1/0.549
Solving this gives:
d ≈ 1.82 parsecs
So, the distance to Bernard's Star is approximately 1.82 parsecs.
