I am the Farthest Planet

I have 4 corners. I have 4 sides.

I have 2 long sides and 2 short sides.

Who I am?

My body is long. I am very healthy.

You can make juice from me. I wear an orange coat. 

I grow underground.

Who I am?

The more of this there is, the less you see. 

What is it?

What has to be broken before you can use it?
