logo Convert orbital elements between epochs

Overview of tools for asteroid observers on this site

Use the form below to convert orbital elements from one epoch to another. (This will usually be between an 'historical' epoch and J2000, but any conversion is possible.) Only the ascending node (Ω), argument of periapsis (ω), and inclination (ι) are affected by the epoch; the other elements are unchanged.

Ascending node (Ω):

Argument of periapsis (ω):

Inclination (ι):

Starting epoch (year): Ending epoch (year):
