You do a diameter circle!!
It is half of the diameter or radius = diameter/2
The cord of a circle that contains the center of that circle is a diameter of that circle.
The diameter is the measurement of a line that goes right through a circle, through the centre point. In cases where we have a ring or some other such object with multiple circles, we would have an external diameter and an internal diameter. The internal diameter is the diameter of the inner circle. The external diameter is the diameter of the outer circle.
Radius = Diameter/2 Diameter = 2* Radius
NO it is not a moon it is an astroid
well, according to my reseach ceres' temperature is -220 F (-176 C)(Fast Fact:ceres' is the largest body in the astroid belt and its diameter is 950 KM(590 mi)
It will go 'bang' when it hits something.

It was an astroid where there was a landing
An asteroid (not "astroid" - watch the spelling) and a meteoride is basically the same; if it has more than about 10 meters in diameter it is called an asteroid. A meteor is the name given to a meteorite that falls into Earth's atmosphere.
