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

| position_angle=position angle
| semimajor=semimajor axis
| 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)
| inclination=orbital inclination
| ang_dist=angular distance
| long_peri=longitude of periastron

This can be preceded or followed by one or more of the following templates:

• {{Planetbox character}}
• {{Planetbox discovery}}
• {{Planetbox catalog}}

The list should then be closed with a {{Planetbox end}} template.
