Could it be that all the stars we see in the sky no longer exist?

I don’t know whether stars nearest to the sun than Proxima Centauri can be still found. However, in our neighborhood within 10 pc there have been discovered lots of stars in the last years.

Unless a star was someohow "special" (a brown dwarf or something), we'd absolutely see/detect it if it was closer than 4.5ly.thomate1 said:Any way the closest star alpha centurai is invisible to naked eye.

Since its only idle speculation and exists only in my head, it can be whatever I want it to be. I call it "Bob". However, it can be said with some certainty that it is not the "Nemesis" or "Planet X," or whatever that crackpots have been claiming for the past several years. That star doesn't exist (either).nightcleaner said:Would that little brown companion star be Nemesis?

Why do you have to call it Bob? Can't you call it Quincy, or Aloysius, or something?russ_watters said:Since its only idle speculation and exists only in my head, it can be whatever I want it to be.

Having zero stars next to the Sun refers to the fact that there are no other stars in our solar system besides the Sun. The Sun is the only star in our solar system and all other objects, such as planets and moons, orbit around it.
Yes, there are many other stars in our galaxy, the Milky Way, that are relatively close to our Sun. Some of the closest stars to the Sun include Alpha Centauri, Proxima Centauri, and Barnard's Star.
The closest stars to the Sun are about 4.2 light years away, which is equivalent to approximately 25 trillion miles. This distance may seem vast, but in terms of the vastness of the universe, it is relatively close.
The Sun is the only star in our solar system because it formed from a collapsing cloud of gas and dust, which allowed it to become hot and dense enough to ignite nuclear fusion and become a star. Other objects in our solar system, such as planets and moons, formed from the leftover material of this process.
It is highly unlikely that other stars will form in our solar system in the future. The conditions that allowed the Sun to form as a star are not present in our solar system anymore. However, it is possible that our Sun could capture other stars or objects from outside our solar system in the future.
