Contested deletion[edit]

This article should not be speedily deleted for lack of asserted importance because... (your reason here) --2A00:23C4:BC0C:6A00:A05F:C22B:9D9B:A5B1 (talk) 04:46, 16 July 2020 (UTC)[reply]

Gliese 3470 has one confirmed planet, Gliese 3470 b, and that planet already has its own Wikipedia page, since November 2015. It would be highly unorthodox, and very frustrating for readers, for Wikipedia to have an article about the planet but not a complimentary one about its parent star. Also, if confirmed, Gliese 3470 c would become the very first exoplanet solely discovered by amateur astronomers. This candidate planet orbits inside the habitable zone, receiving about the same amount of light as the Earth does. Its discovery makes the star, and its properties, even more interesting and therefore paritcularly notable.

KPS-1b wasn't fully discovered by amateurs[edit]

KPS-1b was discovered with data gathered by amateurs, but the project is run by Ural State Technical University.

Unlikely this project, the candidate GJ 3470 c has been discovered through the Habitable Exoplanet Hunting Project, a program fully managed by amateur astronomers. Plus, all the data reported in the GJ 3470 c candidate paper was gathered by amateur astronomers.

For all these reasons, I suggest this edition:

KPS-1b has been the first exoplanet discovered with data gathered by amateur astronomers through a project led by a University, whereas GJ 3470 c, if confirmed, it would be the first exoplanet fully discovered by amateur astronomers

The claims of additional planets are not credible[edit]

For one, Wikipedia doesn't consider arXiv to inherently be a reliable source (WP:ARXIV), which was the reason given for the removal of the new planet claim by an IP editor before it was added back by another IP editor.

Even if you consider the new paper on its own, actually reading it beyond a glance at the abstract should make it clear it's not credible and wouldn't pass peer review. The reference section alone cites this Wikipedia article(!!!), links to "arxive.org" for the earlier paper, and the citation to Kipping et al. 2022 has an incomplete link and misspells the lead author's name.

In any case, data from TESS contradicts the existence of these planets. In some edit summaries elsewhere I linked to a Twitter post saying that a refutation had been submitted to arXiv, but this still hasn't appeared. For now I've removed the additional planets from the planetbox, but kept the text (with some small tweaks), which can hopefully be added to in the future once a refutation appears.
