  1. Skenbara magnitud Måttenhet för ljusstyrkan av en himlakropp som den uppfattas från jorden

  2. Opposition Två himlakroppar ligger i opposition när de befinner sig på motsatta sida av himlen sedd från Jorden

  3. Astronomiska enhet Avståndet mellan Jorden och Solen (AU)

  4. Excentricitet Omloppsbanan < 1 = ellips Omloppsbanan = 1 = cirkel
