What these measurements mean

These comparisons use the reported catalog values. They are interpretations and calculations, not additional observations.

Size in perspective
At the reported radius, a spherical model gives about 4,210 times Earth's volume. This is the radius ratio cubed, not a mass comparison. The radius alone cannot establish whether this world has a rocky surface or a thick gaseous envelope.
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.
