3i atlas could be called a star
?

No, the interstellar object 3I/ATLAS cannot be called a star. It is largely believed to be a comet, or at the very least, a small, rocky body.
Here's a breakdown of why 3I/ATLAS is not a star:
Composition: A star is a massive, luminous ball of plasma, primarily composed of hydrogen and helium, that is held together by its own gravity. It generates energy through nuclear fusion in its core. 3I/ATLAS, on the other hand, is made of rock and ice and does not produce its own light.
Appearance: A star appears as a point of light in telescope images. 3I/ATLAS has a "fuzzy" appearance, known as a coma, which is a cloud of gas and dust that sublimates off its surface as it is heated by the Sun.
Trajectory: 3I/ATLAS is following an unbound, hyperbolic trajectory past the Sun, meaning it is not gravitationally bound to our star and is simply passing through our solar system. A star would be in a stable orbit around a larger mass, or in a specific location within a galaxy.
Origin: 3I/ATLAS was ejected from another star system and has been drifting through interstellar space for potentially billions of years.
In conclusion, although 3I/ATLAS is an interstellar visitor, it is not a star. It is a comet or other small body that was flung out of its original solar system.
