Comment: This draft has been resubmitted without any visible improvement, or with very little improvement. If you do not know what is needed to improve this draft, please ask for advice rather than making minor improvements and resubmitting. You may ask for advice on how to improve this draft at the Articles for Creation help desk or the Teahouse or on the talk pages of any of the declining reviewers. (The declining reviewers may also advise you to visit the help desk.)If this draft is resubmitted without any improvement or with very little improvement again, it is likely to be rejected, and it may be nominated for deletion, or a topic-ban may even be requested against further submission by the responsible editor.This draft, as written, does not appear to indicate that the appropriate notability criterion is satisfied. In particular, this draft does not appear to indicate that WP:NASTRO is satisfied. If one of the criteria is satisfied, please revise this draft appropriately, with a reliable source, if necessary stating on the talk page or in AFC comments which criterion is met, and resubmit. It is the responsibility of the submitter to show that a subject satisfies a notability criterion. You may ask for advice about the notability criteria at the Teahouse.In particular, see and refer to WP:NASTRO for notability, which is the guideline that the subject should be evaluated against.

- Comment: Note to AFC Reviewers: This draft is for a title that was previously an article, but was then cut down to a redirect. If this draft is accepted, the history should be preserved. Do not tag the redirect for G6. If you find that this draft should be accepted, and do not have the Page Mover privilege, please request assistance in moving the redirect to preserve the history. Reviewers should check the history and verify whether there was a consensus to cut the article down to a redirect, or whether the action was taken boldly without discussion. If there was a consensus for the cutdown, do not accept this draft without verifying that the draft improves the article or that consensus has changed. If in doubt, please discuss.As was noted when this draft was declined on 11 August, the coverage of this exoplanet appears to be primary. There does not appear to be significant secondary coverage. The planets of Beta Pictoris are described in the article on Beta Pictoris.If an expanded version of this draft is accepted, the redirect should not be deleted, but moved to preserve history.

Beta Pictoris d (abbreviated as B Pic d) is the third planet from the star Beta Pictoris. Beta Pictoris d was discovered in June 2026, by JWST..[2]. Beta Pictoris d obits at about 26AU from its star and takes 91 years to orbit it [3]. It is 64 light years from Earth and is very young only about 20-26 million years old [4]
Mass and Radius
[edit]Beta Pictoris d is estimated to have a mass of 2-4 Jupiter masses and because of this mass it is considered to be a Super-Jupiter [5] It also has a radius or 1.26 Jupiter radii or about 88,100 kilometers in radius [5]
Atmospheric Composition
[edit]Beta Pictoris d's atmosphere is made of Hydrogen, Helium, Carbon dioxide, Carbon Monoxide, Water vapor and Methane giving it its high Metallicity[1]
Discovery
[edit]Beta Pictoris d was found by JWST while observing one of the other closer in planets through direct imaging by mistake, this makes Beta Pictoris the second system after HR8799 to have more than 2 directly imaged planets[6] Beta Pictoris d is 100 times fainter than its neighbor because of its size being much smaller therefore giving out less internal heat [7], as seen as this artist's impression of the Beta Pictoris System with Beta Pictoris d on the right

This is another direct image of Beta Pictoris b and d with the dotted-blue line being Neptune's orbit

Color in infrared
[edit]Beta Pictoris d likely has a color as seen through infrared telescopes as a Deep red color but from human eye we cannot see this Deep Red Color from the human eye.[1] This red color formed because of the abundance of Carbon dioxide and its high metallicity of its atmosphere [1]
