What these measurements mean
These comparisons use the reported catalog values. They are interpretations and calculations, not additional observations.
- A year on this world
- One orbit lasts about 2.33 Earth years. This comparison uses the reported orbital period. It does not measure the planet's rotation or the length of its day.
- What the mass can tell you
- M sin i is a lower bound on the true mass because the viewing angle affects the radial-velocity measurement. Do not treat it as an exact mass or use it to claim a measured density.
