Appreciated. Is that "Radius of planet 581 in comparison to Earth"--i.e. 1.5--and the planet's gravitation is also in comparison to Earth's? Otherwise, why would Earth's density factor in?

[BGHater]

The Radius is subjective to the Density of 581 and relating to the Radii of Earth.

Earth’s density is factored so we can get a ratio relating to the Gravitational factor of Earth.

For example:

Jupiter density 1.33
Earth Density 5.5
Radius of Jupiter is 11 earth radii

Jupiter= (1.33/5.5) * 11

Jupiter has 2.6 of Earth’s gravity
