right ascention/arc-second

[chill85]

1. Where in the sky is the right ascention equal to zero?(in terms of the ecliptic/constellation)
2. How does an arc-second compare to an arc-minute and a degree?

This sounds like homework questions. If you will Google on the terms you are using, you will find a lot of information on your own. Then post again if there are some things that are unclear. The Internet is a great reference resource, but you have to use it as such instead of asking for the answers. If you get an answer, and pass it in as your own work without understanding it, you're short-changing yourself.
