Abstract

The main aim of this work is to establish a relation between various physical characteristics of a planet, which were previously considered independent. The proposed ‘relation between planetary parameters’ (RPP) elegantly shows that the ratio of axial tilt to the product of rotation period and square of the orbit radius is always constant for a planet. We also show that the relation can be obtained from a more fundamental law of physics, the principle of conservation of angular momentum. In other words, we can realize this relation by conserving the total angular momentum of a planet. At last, we discuss an application of this relation.

Keywords: Angular momentum, planetary physical parameters
