Transition between gas giant planets and terrestrial planets?

[edit]

With more mass or originating in a cooler part of the Solar System, Earth would have been capable of holding helium and becoming a "warm Neptune"... and could even maintain the helium that arises from the radioactive decay of long-lived isotopes of thorium and uranium. Helium from such sources escapes the Earth's atmosphere.Pbrower2a (talk) 17:49, 7 September 2017 (UTC)Reply

Yes these are indeed interesting scenarios. It is currently a hot astrophysical topic, if the gas giants of our Solar System contain a rocky Earth-like core or not. And to know more about the interiors of gas giants is a major motive for new missions to the Outer Solar System. RhinoMind (talk) 04:14, 9 September 2017 (UTC)Reply
It seems implausible that Helium from radioactive decays alone could create a Helium planet. RhinoMind (talk) 04:18, 9 September 2017 (UTC)Reply

Clutter

[edit]

“There are several theoretical ideas for how a helium planet might form.” I changed “theoretical ideas” to “hypotheses”, to remove clutter. Likewise, in “The Gliese 436 b exoplanet is a candidate helium planet” i took out “The” and “exoplanet”; and in “This characteristic contrasts ordinary gas giants such as Jupiter and Saturn...” i changed “characteristic contrasts” to “contrasts with”. Okay?--Solomonfromfinland (talk) 05:48, 22 April 2018 (UTC)Reply

There are several hypotheses

[edit]

@Daß Wölf: please, don’t delete a valid introductory phrase for a section. Here is not a paper encyclopedia. Incnis Mrsi (talk) 08:58, 10 August 2019 (UTC)Reply

It struck me as redundant, it doesn't actually convey any more information than would changing the title of the main section to "Formation hypotheses" or something similar. DaßWölf 00:05, 11 August 2019 (UTC)Reply

Picture of hydrogen evaporation

[edit]

The picture of hydrogen evaporation seems to have a mistake, the second and third frames are identical and presumably the third one shoukd be different (showing complete loss of hydrogen and carbon in the form of oxides). Olthe3rd1 (talk) 23:16, 24 June 2023 (UTC)Reply
