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.
Syntax for this template:
{{Planetbox orbit
| separation = <!--observed separation, in astronomical units (AU)-->
| position_angle = <!--position angle, in degrees-->
| semimajor = <!--semimajor axis, in astronomical units (AU)-->
| semimajor_gigameter = <!--semimajor axis, in gigameters (Gm) (optional, can use semimajor instead)-->
| semimajor_microparsec = <!--semimajor axis, in microparsecs (μpc) (optional, can use semimajor instead)-->
| semimajor_no_units = <!--semimajor axis (no units provided by template)-->
| periastron = <!--periastron in astronomical units (AU)-->
| periastron_gigameter = <!--periastron in gigameters (Gm) (optional, can use periastron instead)-->
| periastron_microparsec = <!--periastron in microparsecs (μpc) (optional, can use periastron instead)-->
| apastron = <!--apastron in astronomical units (AU)-->
| apastron_gigameter = <!--apastron in gigameters (Gm) (optional, can use apastron instead)-->
| apastron_microparsec = <!--apastron in microparsecs (μpc) (optional, can use apastron instead)-->
| 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)-->
| period_megasecond = <!--orbital period in megaseconds (optional, can use period instead)-->
| inclination = <!--orbital inclination, in degrees-->
| ang_dist = <!--angular distance, in milliarcseconds (mas)-->
| long_peri = <!--longitude of periastron, in degrees-->
| arg_peri = <!--argument of periastron, in degrees-->
| 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_approach = <!--time of closest approach (Julian date, JD)-->
| semi-amp = <!--velocity semi-amplitude (m/s)-->
}}
This can be preceded or followed by one or more of the following templates:
- {{Planetbox image}}
- {{Planetbox star}}
- {{Planetbox orbit}}
- {{Planetbox character}}
- {{Planetbox discovery}}
- {{Planetbox catalog}}
The list should then be closed with a {{Planetbox end}} template.
