If a massive body fails to become a star could it still suport planetary system?

AI Thread Summary
A massive body that fails to become a star can still support a planetary system, often referred to as a "mini system." Objects with less than approximately 0.08 solar masses do not initiate fusion but can still host orbiting bodies. These systems can resemble those of gas giants like Jupiter and Saturn, with moons acting as planets. The gravitational influence of the massive body allows for the formation of these orbiting objects. Thus, even non-stellar bodies can maintain complex systems of satellites or planets.

Sure, it would be called a "mini system" like Jupiter, Saturn, etc. with numerous moons (planets) orbiting around. Anything under ~0.08 solar masses won't start fusion, but other objects can still form and orbit.

Thread 'Asteroid 2024 YR4 has a 1% risk of a multi-megaton impact in 2032 (now ruled out)'

Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons. Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
