This draft's references do not show that the subject meets Wikipedia's criteria for inclusion. The draft requires multiple published secondary sources that:

provide significant coverage: discuss the subject in detail, not just brief mentions or routine announcements;
are reliable: from reputable outlets with editorial oversight;
are independent: not connected to the subject, such as interviews, press releases, the subject's own website, or sponsored content.

Please add references that meet all three of these criteria. If none exist, the subject is not yet suitable for Wikipedia.

If you would like to continue working on the submission, click on the "Edit" tab at the top of the window.
If you have not resolved the issues listed above, your draft will be declined again and potentially deleted.
If you need extra help, please ask us a question at the AfC Help Desk or get live help from experienced editors.
Please do not remove reviewer comments or this notice until the submission is accepted.

Where to get help

If you need help editing or submitting your draft, please ask us a question at the AfC Help Desk or get live help from experienced editors. These venues are only for help with editing and the submission process, not to get reviews.
If you need feedback on your draft, or if the review is taking a lot of time, you can try asking for help on the talk page of a relevant WikiProject. Some WikiProjects are more active than others so a speedy reply is not guaranteed.

Comment: We need to see significant secondary coverage of the subject to warrant a standalone article separate from Beta Pictoris Sulfurboy (talk) 23:55, 11 August 2026 (UTC)

Beta Pictoris d (abbreviated as B Pic d) is the third planet from the star Beta Pictoris. Beta Pictoris d was discovered on June 22, 2026, by JWST ^[2]. Beta Pic 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

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. It has a radius or 1.26 Jupiter radii or about 88,100 kilometers in radius.

Atmospheric Composition

Beta Pictoris d's atmosphere is made of Hydrogen, Helium, Carbon dioxide, Carbon Monoxide and Methane ^[1]

Discovery

Beta Pic d was found by JWST while observing Beta Pic b through direct imaging

This is an artist's impression of the Beta Pic System with beta Pic d on the right.

.

Color in infrared

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]
