- Comment: Editor: Sources #1 and #2 appear to be the same? And source #4 doesn't mention CoRoT-8 at all as far as I can see? This is a well structured draft but I would really love to see at least one more source that discusses this star or the planet. Qcne (talk) 17:23, 31 August 2023 (UTC)
- Comment: See WP:NASTCRIT for guidelines on the notability of astronomical objects. Furthermore, please provide a different link to the journal that study was published in, which does not use Arxiv, per WP:ArXiv. ARandomName123 (talk)Ping me! 21:26, 23 August 2023 (UTC)

CoRoT-8 is a star in the constellation Aquila at a distance of about 1239 light-years from us. At least one planet revolves around the star.
Characteristics
CoRoT-8 is an orange dwarf which has 0.88 solar masses and 0.77 solar radius. [1]. By astronomical standards, this is already a rather young star compared to the Sun: its age is about 3 billion years. It got its name in honor of the CoRoT space telescope, with the help of which its planetary companion was discovered.
Planetary system
In 2010, a group of astronomers working within the CoRoT program announced the discovery of the planet CoRoT-8b in this system. It is a hot gas giant, similar in mass and size to Saturn. The planet orbits at a distance of about 0.06 AU. e. from the parent star, while making a complete revolution in 6.21 days. [2][3][4]
