Can someone please explain how Earth has acquired an ascending node? How does it pass through the plane of its own orbit? 142.177.19.31 05:48, 24 Aug 2004 (UTC)
I wondered that myself. I assumed it was because these numbers are for Epoch 2000.0. There's a discussion on one of these boards about it, I forgot which one. Now, what is the difference between the right ascension of the ascending node and the angle between the first point of Aries and the ascending node? I agree your wording is probably clearer, but I don't think there's a technical difference between the two values. I originally got the data from RedShift, and it stated that the right ascension is defined as the angle between a position and the first point of Aries on the celestial sphere. As long as it is assumed the celestial sphere is projected from the sun, the two seem identical.
