You think that you spot a new planet with your telescope. For the space object to be classified as a planet, you know that it must.

Below

Explanation:

1) It must orbit a sun (solarsystem.nasa.gov)

2) Has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a sphere (er.jsc.nasa.gov)

3) It must be big enough that its gravity cleared away any other objects of a similar size near its orbit around the Sun. (solarsystem.nasa.gov)

4) Has cleared the neighborhood around its orbit. (solarsystem.nasa.gov)

Hope this helps :))
