Explanation:

Ultraviolet rays: They are invisible rays that are part of the energy that comes from the sun. The ultraviolet radiation that reaches the surface of the Earth is composed of two types of rays called UVA and UVB.

The answer is: Ultraviolet.

The energy of X-rays in general lies between ultraviolet radiation and naturally occurring gamma rays.

The answer is: They are less dangerous than ultraviolet rays.

the farther away the object is from the central star (the sun) it's gravitainal pull on the object is weaker when it is farther
