This template is part of a group of templates that are used to display information about a specific extrasolar planet. The {{Planetbox begin}} is always the first in the list, while {{Planetbox end}} is always the last in the list. This particular template can be used as follows:

{{Planetbox orbit
| epoch = <!--epoch the orbit is valid for-->
| semimajor = <!--semimajor axis, in astronomical units (AU)-->
| semimajor_gigameter = <!--semimajor axis, in gigameters (Gm) (optional)-->
| semimajor_no_units = <!--semimajor axis (no units provided by template)-->
| periastron = <!--periastron in astronomical units (AU)-->
| periastron_gigameter = <!--periastron in gigameters (Gm) (optional)-->
| apastron = <!--apastron in astronomical units (AU)-->
| apastron_gigameter = <!--apastron in gigameters (Gm) (optional)-->
| eccentricity = <!--orbital eccentricity-->
| period = <!--orbital period in days (optional, can use period_year instead)-->
| period_year = <!--orbital period in years (optional, can use period instead)-->
| speed = <!--orbital speed in kilometers per second (km/s)-->
| inclination = <!--orbital inclination, in degrees-->
| node = <!--longitude of the node, in degrees-->
| arg_peri = <!--argument of periastron, in degrees-->
| mean_anomaly = <!--mean anomaly, in degrees (always specify epoch when using this field, which should only be used for dynamical fits)-->
| t_peri = <!--time of periastron (Julian date, JD; can use t_peri_no_jd instead)-->
| t_peri_no_jd = <!--time of periastron (no calendar specified; can use t_peri instead)-->
| t_transit = <!--time of transit (Julian date, JD; can use t_transit_no_jd instead))-->
| t_transit_no_jd = <!--time of transit (no calendar specified; can use t_transit instead)-->
| t_eclipse = <!--time of eclipse (Julian date, JD; can use t_eclipse_no_jd instead)-->
| t_eclipse_no_jd = <!--time of eclipse (no calendar specified; can use t_eclipse instead)-->
| semi-amp = <!--velocity semi-amplitude (m/s)-->
