This composite image shows an exoplanet (2M1207b, the red spot on the lower left), orbiting the brown dwarf 2M1207 (centre). 2M1207b is a Jupiter-like planet. It orbits the brown dwarf at a distance nearly twice as far as Neptune is from the Sun. Credit: ESO.

This radiation mathematics/problem set is a series of mathematical problems that use dimensions.

Notation: let the symbol $R_{\oplus }$ indicate the Earth's radius.

Notation: let the symbol $R_{J}$ indicate the radius of Jupiter.

Notation: let the symbol $R_{\odot }$ indicate the solar radius.
