ଛାଞ୍ଚ:Orbit
This template allows AstRoBot to update orbital elements automatically, using data from the Heavens-Above and n2yo websites. (Note that due to recent changes to the Heavens Above website, future support for this source may be discontinued).
Do not use this template on articles for spacecraft which are not currently in Earth orbit. Please read the instructions fully before setting up automatic updates. Consider discussing updates on the article's talk page or at the WikiProject talk page beforehand to ensure AstRoBot is suitable for that article.
Usage
ସମ୍ପାଦନାBefore using this template, it is recommended that you begin a discussion on the article's talk page and determine whether there is a consensus for that article to contain automatically updated orbital elements.
- {{Orbit|<parameter name>|<initial value>}} to display a parameter in the article
- {{Orbit|<parameter name>|<initial value>|hide}} for a control parameter which is not displayed
Two control parameters; epoch and satcat are required for the bot to retrieve data. It is strongly recommended that they be displayed in the article, however the hide parameter is available if it is needed.
The template can be nested inside others, such as {{convert}} for the apogee, perigee, altitude at epoch and semi-major axis:
- {{Convert|{{Orbit|<parameter name>|<initial value>}}|km|mi}}
Use of this template for spacecraft outside Earth orbit is not recommended.

Supported parameters
ସମ୍ପାଦନା| Data | Parameter name | Infobox field | Units | Remarks |
|---|---|---|---|---|
| Argument of perigee | arg of perigee | orbit_arg_periapsis | degrees | |
| Apogee | apogee | orbit_apoapsis | kilometres | |
| Altitude at epoch | altitude at epoch | (none) | kilometres | |
| Eccentricity | eccentricity | orbit_eccentricity | dimensionless | |
| Epoch date | epoch | orbit_epoch | n/a (date) | required |
| Epoch time | epoch time | included in orbit_epoch | n/a (time) | Include, along with epoch, for greater precision |
| Inclination | inclination | orbit_inclination | degrees | |
| Mean anomaly | mean anomaly | orbit_mean_anomaly | degrees | |
| True anomaly | true anomaly | (none) | degrees | |
| Eccentric anomaly | eccentric anomaly | (none) | degrees | |
| Number of orbits completed | orbits | orbits_completed orbit_rev_number |
dimensionless | Updates two infobox fields - orbits_completed is intended as a total over the spacecraft's lifetime, while rev_number is specific to the displayed elset. From the bot's perspective, using the most up-to-date information, they are identical |
| Perigee | perigee | periapsis | kilometres | |
| Right ascension of the ascending node | RAAN | orbit_RAAN | degrees | |
| Speed at epoch | speed at epoch | n/a | kilometres per second | Not suitable for eccentric orbits |
| Average Speed | average speed | orbit_velocity | kilometres per second | |
| Mean motion | mean motion | orbit_mean_motion | dimensionless | Given in orbits per day |
| Orbital period | period | orbit_period | minutes | |
| Semi-major axis | semimajor axis | orbit_semimajor | kilometres | |
| Citation | ref | (none) | n/a (string) | Provides a reference to the page the orbital elements were obtained from. Must only include a reference, wrapped in <ref> tags |
| Satellite Catalog Number | satcat | SATCAT | n/a (string) | Required, not updated (constant) - used to identify satellite |
| Data source | datasource | n/a | n/a | HN, NH, H or N Specifies whether the bot uses Heavens-Above (H) or n2yo (N) for orbit data, and if both are selected the order of preference. Defaults to NH (n2yo then heavens-above) |
