TOI-849 b is an exoplanet orbiting the late-G type star TOI-849. It is a candidate chthonian planet, the exposed core of a gas giant that had much of its atmosphere stripped away. [1] It is around 700 light-years away from Earth. [2]

2024年10月24日 · TOI-849 b is a gas giant exoplanet that orbits a K-type star. Its mass is 0.13152 Jupiters, it takes 0.8 days to complete one orbit of its star, and is 0.0155 AU from its star. Its discovery was announced in 2020.

2020年7月1日 · The roasted world known as TOI-849b is the most massive rocky planet ever observed, with as much as 40 Earths’ worth of material crammed inside.

2020年7月2日 · The newly-discovered planetary core, named TOI-849b, is a gas giant that was either stripped of its gaseous atmosphere or that failed to form one in its early life. An artist’s impression of a Neptune-sized exoplanet.

2020年7月4日 · The planet in question is called TOI-849b, and it's orbiting a Sun-like star called TOI-849. When we figure out exactly what it is, it could help us to better understand what's inside the thick atmospheres of gas and ice giants, like Neptune, and the formation processes of these formidable planets.

2020年9月16日 · TOI-849b, which has a year that lasts 18 hours, is similar in size to Neptune but with a significantly higher mass and density. These contradictory characteristics have led researchers to infer that the exoplanet is the exposed core of what may have started out as a typical gas giant like Jupiter.

2020年7月2日 · This roasted world is known as TOI-849b, the most massive rocky planet ever observed equivalent to over 40 Earth worth of material crammed inside it. Surprisingly, planet TOI-849b's large...

The planetary system TOI-849 hosts at least one planet. This list shows all planetary and stellar components in the system. It gives a quick overview of the hierarchical architecture. This table lists all planets in the system TOI-849. This planet was discovered by Armstrong et al. 2020.

2020年3月23日 · Here we report observations of the planet TOI-849b, which has a radius smaller than Neptune's but an anomalously large mass of 39.1+2.7−2.6 Earth masses and a density of 5.2+0.7−0.8 grams per cubic centimetre, similar to Earth's.
