The discussion revolves around understanding how the radius of a planet affects its mass, particularly when comparing it to Earth's mass and radius. Participants are exploring the implications of changing a planet's radius on its mass while considering density as a factor.
The discussion is ongoing, with participants providing insights into the relationship between volume and mass. There is a suggestion to think about the volume ratio and its effect on mass, indicating a productive direction for further exploration.
Participants are working under the assumption that the planet has the same density as Earth, and there is a focus on the mathematical relationships involved in calculating mass from volume.

I know this is a dumb question but if the radius of a planet is one-fifth of the Earth . what is the mass of the planet.
Earth mass => 5.97 *1024
earth radius => 6.38 *106
The Attempt at a Solution
my answer: 5.97 *1024(1/10)
