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 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b. I start this...
