An orbital node refers to a point in space related to the orbit of a celestial body. In the context of orbital mechanics, the term usually applies to two specific points known as the ascending node and the descending node: 1. **Ascending Node**: This is the point at which an object in orbit moves from a lower orbital plane to a higher one, crossing the reference plane (such as the equatorial plane of a planet) from south to north.
