Where Can I Find Transit Times for Astronomical Objects?

-- | April 28, 2016

Question: Is there a way or a program available that will tell me what point on earth is 90° below it. For example for the sun and moon they show when the sun is 90° above a certain location. Can I find out the same thing for mercury and venus? — Steve

Answer: I think what you are asking for are the times when astronomical objects are at their highest point in the sky, otherwise known as “transit”. The Naval Observatory Data Services provides a nice web page which includes links to quite a few calculators which allow one to determine rise, set, and transit times for many astronomical objects.
