Suppose that two stars in a binary star system are separated by a distance of 80 million kilometers and are located at a distance of 160 light years from earth. What is the angular separation of the two stars? Give your answer in arcseconds
I am trying to plot the ground tracks of an orbit. But I am having a problem with finding the longitude. The equation for the longitude is shown in the image. Is the Theta GMST initially zero because the greenwich meridian points to the Aries point (x-axis). How do you calculate alpha or vernal equinox? I saw a formula for alpha which is alpha = arctan(ry/rx), but the formula was for Right Ascension angle. Is the right ascension angle the same as vernal equinox. If not, then what is the formula for vernal equinox.
What would the angle between the Sun and the Earth be if the solar system were viewed from a distance of 1 pc?

The stars in a CCD image include stars in a cluster and stars in front of the cluster (i.e. starts that don't belong to it). One group has parallaxes clustered around of 3 milli-seconds of arc (or "3 mas"). The parallaxes of the other group range from 10 mas to 15 mas. Which group contains the stars in the cluster? Explain your answer.
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.
