Answer:
Kepler's 1st law of planetary motion is called the law of ELLIPSES.
Step-by-step explanation:
Kepler's 1st law of planetary motion can be referred to as the law of ellipses.
An ellipse is a form of an oval shape.
Kepler's 1st law of planetary motion states that every planet moves or rotates around the sun in a ellipses or elliptical orbit.
It is important to know that the sun is the focus or focal point of this ellipse.
Kepler's 1st law of planetary motion also serve as an indicator to show us s that when planet Earth rotates round the sun in an elliptical orbit, the distance between the Earth and Sun changes.
