## What is a TLE (or 2LE or 3LE)?
> **TLE or 2LE**: Two-Line Element Set
> **3LE**: Three-Line Element Set
TLEs are used to describe the orbits of Earth-orbiting objects. They are used by the United States Department of Defense to track objects in orbit.
Recent TLEs for most objects can be found at the following websites:
- [Space-Track](https://www.space-track.org/)
- [Celestrak](https://www.celestrak.com/)
- [N2YO](https://www.n2yo.com/)
