An orbital pole is either end of an imaginary line running through the center of an orbit perpendicular to the orbital plane, projected onto the celestial sphere.
For future exploration, when we have the objective of going to the Moon, it is important to have several possibilities to go there, and within this framework of cooperation to have our own access to orbit around the Moon. Alain-Fournier
I am proud to find, from two astronomical observations, that Chapel Hill lies right in the orbit of Jupiter and his satellites, and that the period of his revolution is about twelve years. William Hooper
In physics, an orbit is the gravitationally curved path of one object around a point or another body, for example the gravitational orbit of a planet around a star.
It seems to me, thinking of it, that there must be some universal plan which set in motion the orbiting of the electrons about the nucleus and the slower, more majestic orbit of the galaxies about one another to the very edge of space. Clifford D. Simak
NASA will send up a big sun shade that will be in orbit between the earth and sun and deflect 2 or 3 percent of the sunshine back into space. It would be cheaper than the international space station. James Lovelock
Now, I've never flown in space; but the folks who have say that on landing day, you know, you've just spent maybe a week and a half, sometimes two weeks in orbit and you're used to the things happening slowly in space. Duane G. Carey
The first two missions have some test objectives, some new capabilities that we're going to try to develop on orbit to possibly be used on later flights. Mark Kelly
The term nadir can also be used to represent the lowest point reached by a celestial body during its apparent orbit around a given point of observation.
We launch when we're kind of in the same orbit that they are in terms of being matched up in inclination in space, and we're just in a little different altitude. Linda M. Godwin
