What is companion star?
Stars often come in groups of two or more. In the case of a binary star (two stars), the two stars move around their common center of mass - one complete orbit every few hours, days, years, or even thousands of years - just like the planets orbit the Sun. Each of these stars would be the "companion" of the other one. One of these stars can become a black hole; in that case, the gravitational situation doesn't really change - the two (the black hole and the star, in this case) will continue orbiting their common center of mass.
How many stars does antares have?
Antares (Alpha Scorpii) is a huge red hypergiant star, with a radius 800 times that of our own sun. There are some bigger stars though, such as Betelgeuse (1180 solar radii) and V354 Cephei (1520 solar radii), but the biggest known star is VY Canis Majoris, which is estimated to have a diameter between 1800 and 2100 times that of our own sun. If it were in the centre of our solar system its edges would almost reach the orbit of Saturn.
What do you call two days per year when the length of a day and night are equal?
I call them the days when Spring and Autumn begin.They are widely but incorrectly called the equinoxes, but the equinoxes arenot events or dates. They are points on the map of the stars.
