Calculating Elongations

Elongations
Did you ever wonder how far apart in degrees two objects are in the sky? If you ever wondered how Venus was above the Sun or how wide is the bowl of the Big Dipper, this is what you are asking. If you supply two coordinate pairs, this tool will tell you how many degrees separate them. While the two coordinate need not be in the same format, they both be in the same system (both Equatorial, or both Ecliptic or both Horizon).

Great Circle Distances
This is almost the same as the tool as Elongations except that a planetary radius must be supplied. The default is for the Earth in kilometers.
