What these measurements mean
These comparisons use the reported catalog values. They are interpretations and calculations, not additional observations.
- A year on this world
- A 365.25-day Earth year spans about 21.3 of these orbits. 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
- Mass describes how much material the planet contains. Inspect the published uncertainty and reference before combining it with a radius to estimate density. Catalog values can come from different studies.
