No, they cannot be both.
Yes and no because when you look up in the sky some of those stars are planets but techinacally they aren't stars.
No. The stars are too hot for molecules to form. That said, some of those stars have planets and some of those planets may have water.
Some planets seem brighter - not all of them. Planets are quite near to us, as compared to the stars.
well for starters, stars don't orbit planets. Planets orbit stars, but some stars don't have planets that orbit them.
No. Planets are objects made of some combination of rock, gas, and/or metal that orbit stars.
Moons orbit planets. Planets orbit stars. Some stars orbit other stars, or orbit their mutual center of gravity. Stars orbit the center of the galaxy. Galaxies may orbit the center of the "galactic group".
Planets orbit stars.
On the contrary! A star has planets, which circulate it. And planets have moons. Stars do not circle planets.
the stars and some of our planets
some do but that is it i am guessing
No. Planets are formed after stars are and in most cases planets are consumed by the same star. Some stars can exist long after they have exhausted their supply of hydrogen and heavier element as red giants. Some even may last over 100 of trillions of years.
On the whole stars are much larger than planets, but there are some dwarf stars that are smaller than giant planets.
