WebThese orbital and astronomical changes repeat on time scales ranging from 26,000 to 100,000 years, and one can calculate their effect on the amount of energy our planet receives from the sun. A scientist named Milutin Milankovitch worked out the theory behind these cycles in the early 20th century, and they are named Milankovitch Cycles after him. WebThe energy of an orbital is calculated from the value of the principal quantum number ‘n’ and the azimuthal quantum number ‘l’.
