#### Orbit determination

• abstract: Orbit determination is a set of techniques for estimating the orbits of objects such as moons, planets, and spacecraft. Determining the orbits of newly observed asteroids is a common usage of these techniques, both so the asteroid can be followed up with future observations, and also to verify that it has not been previously discovered.
