{{Planetary radius
| radius = <!--simplified number of the radius (Jupiter equals 100px)-->
}}
Some planets might have a radius that would be hard to compare to Jupiter. So the option to compare the planet to Earth is possible.
{{Planetary radius
| base = <!--base planet (between Jupiter and Earth [Jupiter automatic])-->
| radius = <!--simplified number of the radius (Jupiter or Earth equals 100px)-->
}}
Other options include choosing which part of the page the template can be placed in, as well as the exoplanets name.
{{Planetary radius
| align = <!--The side of the page the box is on (left/right [left is automatic])-->
| Exoplanet = <!--name of the planet (optional)-->
| radius = <!--simplified number of the radius (Jupiter equals 100px)-->
}}
