GENERAL KNOWLEDGE

Detailed explanation-1: -Complete answer: Binaries are the stars which appear single to the naked eye but are double when seen through a telescope. They are single to naked eye because they are far from us. But, if we see with a telescope we can observe that there are two or double stars .

Detailed explanation-2: -From Earth, it can be seen as a hazy form of stars in the night sky that the naked eye can barely notice. You can see the Milky Way all year, no matter where you are in the world. It’s visible just so long as the sky is clear and the light pollution is minimal.

Detailed explanation-3: -A binary star is a system of two stars that are gravitationally bound to and in orbit around each other. Binary stars in the night sky that are seen as a single object to the naked eye are often resolved using a telescope as separate stars, in which case they are called visual binaries.

Detailed explanation-4: -Considering all the stars visible in all directions around Earth, the upper end on the estimates seems to be about 10, 000 visible stars. Other estimates place the number of stars visible to the eye alone – surrounding the entire Earth – at more like 5, 000. At any given time, half of Earth is in daylight.
