What 2 rules do scientists use to determine if something is a planet. * Please use your own words to answer the question* THANK YOU VERY MUCH

1. It must orbit a star (in our cosmic neighborhood, the Sun).

2. It must be big enough that its gravity cleared away any other objects of a similar size near its orbit around the Sun.

Explanation:

I hope this helps!

v=ir = 3x15 =45 v

grav forces affect all objects magnetic forces affect magnetic objects and electric currents
