Does the star Betelgeuse have any planets?

Check out this answer from Consensus:

While the data provided does not directly address the presence of planets around Betelgeuse, the environmental conditions and stellar characteristics described make it a challenging place for planets to form or persist. The star’s future as a supernova candidate also raises questions about the long-term prospects for any planetary companions. Further research and observations are needed to conclusively determine if Betelgeuse has any planets in its orbit.


The Search for Planets Around Betelgeuse

Betelgeuse, a red supergiant star located in the constellation of Orion, has long intrigued astronomers with its massive size, brightness, and potential for a supernova explosion. However, the question of whether Betelgeuse hosts any planets remains an area of active research and speculation.

Stellar Characteristics and Environment of Betelgeuse

Betelgeuse is a well-studied star with a complex history and environment. It is believed to be the outcome of a past merger in a binary system, which could explain its fast rotation and large space velocity1. The star’s surface shows complex asymmetries and brightness variations, which have been attributed to convective surface hotspots and possibly a newly formed dust halo2. These features, along with the star’s powerful stellar wind and the resulting bow shock as it moves through the interstellar medium, create a dynamic and challenging environment for planet formation and survival3.

Potential for Planetary Systems

The tumultuous history and active surface of Betelgeuse, including its pulsation dynamics and mass loss, suggest that any potential planetary system would have to endure extreme conditions45. The presence of a circumstellar envelope and dust indicates that material is being expelled from the star, which could impact planet formation or the stability of existing planets7. High-resolution imaging has revealed spots on the star’s surface, which could be indicative of magnetic activity and stellar flares, further complicating the environment for planets6.

Distance and Mass Estimates of Betelgeuse

Accurate distance and mass estimates are crucial for understanding the potential for planets around Betelgeuse. Recent studies have provided new insights into the star’s distance, suggesting it is farther away than previously thought9. This has implications for the star’s interaction with its environment and the conditions that would be faced by any orbiting planets.


Does the star Betelgeuse have any planets?

We don’t know if it has any planets. At least we haven’t yet been able to detect any. The physics of planet formation are the same for all stars and planets seem to be ubiquitous so it is not entirely unreasonable to expect that Betelgeuse might host some. That said, there are good reasons why any potential planets around it would probably not be friendly for life as we know it.
