Milankovitch Theory In 1938, Serbian mathematician and Milutin Milankovitch , astronomer, hand- computed insolation at 60 ° N based on orbital variations for two 6- month seasons (summer & winter)

Milankovitch Theory He computed variations in three primary orbital parameters: Obliquity , Eccentricity , and Precession of the Longitude of Perihelion in relation to the Moving Equinox (commonly just called Precession)
Milankovitch Theory Eccentricity involves the variations associated with the shape of the Earth’s orbit (oblique to circular). The primary cycle of eccentricity is 93,000 years with a secondary cycle at 400,000 years.

Milankovitch Theory Obliquity refers to the variations in the axial tilt of the Earth. This orbital component has a cycle of 42,000 years for the Earth to shift from an axial tilt of 22.1 ° to 24.5 ° and back.
Milankovitch Theory Precession of the Longitude of Perihelion in relation to the Moving Equinox is the most complex of the three mechanisms. Basically it refers to what season is perihelion occurring in as a function of the orientation (or “wobble”) of the Earth’s axis.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
