Talk:Proxima Centauri d

"twice the mass of Mars" is wrong
If Proxima D is a quarter the mass of Earth, then "twice the mass of Mars" is wrong, as Mars has 38% of Earth's mass. Thus the right sentence would be "... half the mass of Mars" 2A02:3032:2:6498:1:1:CF4:33D8 (talk) 23:30, 22 May 2023 (UTC)


 * Wrong. Mars has 10.7% of Earth's mass, as stated in its article. Do you have a reliable source stating that Mars has 38% of Earth's mass? SevenSpheres (talk) 23:50, 22 May 2023 (UTC)
 * OK, you're right.
 * The mass is only 10% of Earth's.
 * But it's misleading. Because then people think its (surface) gravity is also only 10%.
 * But its (surface) gravity is 38% of Earth's. Because it is smaller than Earth. And thus one stands closer to it's center.
 * If talking about mass, one should also mention (surface) gravity, because that's what people are usually googling for. They want to know how heavy is a human walking on such a planet.
 * Mass is misleading.
 * But besides that, you're right.
 * I'm Sorry 2A02:3032:2:6498:1:1:CF4:33D8 (talk) 02:22, 23 May 2023 (UTC)
 * Without a measured radius for Proxima d, any surface gravity could only be an estimate. SevenSpheres (talk) 03:09, 23 May 2023 (UTC)
 * Yes, you're right 2A02:3032:2:6498:1:1:CF4:33D8 (talk) 07:01, 23 May 2023 (UTC)
