- (The answer for 1 is not 0.000095 solar masses/year)What would the angle between the Sun and the Earth be if the solar system were viewed from a distance of 1 pc?As seen from earth the sun has an apparent magnitude and of about -26.7 what is the apparent magnitude of the sun as eeen from Saturn about 10AU away?
- There are two parts to this question. I need to know how many times fainter Venus is from a distance of 6 pc and what the apparent magnitude would be as well! Thank you!!A planet was recently discovered orbiting the star Proxima Centauri, with an orbital radius of 0.05 AU. As seen from Earth, what is the maximum angular separation between this planet and Proxima Centauri, in arcseconds? The distance to Proxima Centauri is 4.24 light-years.Given a star has a absolute magnitude of 2.5 and an apparent magnitude of 10.0. With this data calculate the distance.
