Can a planet exist without a star
WebThat information can then be compared to modeling data to gather all kinds of information about the planet. Let's take the planet Tau Boötis b as an example. Found in 1996, Tau Boötis b was the first planet found not by watching its transit (it doesn't pass in front of its star), but by noticing it exerted a bit of a pull on its star. WebAn intergalactic star, also known as an intracluster star or a rogue star, is a star not gravitationally bound to any galaxy.Although a source of much discussion in the scientific community during the late 1990s, intergalactic stars are now generally thought to have originated in galaxies, like other stars, before being expelled as the result of either …

WebOct 14, 2024 · Since the distance to the nearest star outside of our solar system is about 70,000 times greater than the distance to Jupiter, "all stars are effectively out of reach." WebAnswer (1 of 2): Yes. These are called Rogue Stars and we've seen hundreds of them. It's unlikely a star would be formed in intergalactic space, as you'd need a lot of coalesced matter (i.e. in a stellar nursery). But its possible for hypervelocity stars to be ejected from a galaxy and wander of...
Interstellar planets generate little heat and are not heated by a star. However, in 1998, David J. Stevenson theorized that some planet-sized objects adrift in interstellar space might sustain a thick atmosphere that would not freeze out. He proposed that these atmospheres would be preserved by the pressure-induced far-infrared radiation opacity of a thick hydrogen-containing atmosphere.
