{{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)-->}}
Here is the full syntax
