Changes in tilt of earth’s axis

by

This topic shall discuss the changes in earth axis i.e. cyclic changes in obliquity of earth’s axis or in other words, changes in tilt of earth’s axis … This topic is in continuity with the previous one of “Changes in earth’s orbit” … In this topic we shall calculate time span of cyclic changes in tilt … Read more

Changes in earth’s orbit

by

Here we shall discuss cyclic changes in Earth’s orbit … Here we shall derive the time span for a cycle of change in earth’s revolution orbit around the sun (or time span of cyclic changes in Earth’s orbit or cyclic changes in Earth’s orbital eccentricity) … The path of earth also expands and contracts by ratios … Read more
