| 2. | Pluto has a very unusual orbit. Once every 248 Earth years, Pluto swings inside the orbit of Neptune. It stays there for twenty years. During those twenty years, Pluto is closer to the Sun than Neptune. | |
| 3. | Due to Triton's retrograde orbit, its density, and its composition, astronomers theorize that Triton was not originally a satellite of Neptune, but was captured by Neptune's gravitational pull, forcing it into an orbit around the planet. | |
| 4. | Most satellites, including the Hubble Space Telescope, orbit in a low Earth orbit of just a few hundred kilometers altitude. | |
| 5. | Chandra has an elliptical orbit which takes it more than 138,000 kilometers from Earth and then back to within 9600 kilometers of Earth. Chandra travels more than one-third of the way to the Moon with each orbit! | |
| 6. | Halley has a highly elongated orbit that takes it very close to the Sun and then flings it out into the outer solar system, well past the orbit of Pluto. | |
