We don't actually know that they don't; however, as hypergiants are quite massive, it's hard to detect the slight perturbation a planet would have on one.
Hypergiants are very rare and they have a ver short lifespan, and thus they are difficult to observe.
Red hypergiants.
Depends on how you want to classify bigger. Mass or diameter. VY Canis Majoris is a red hypergiant and has the largest diameter of any known star. See related questions for both answers
Hypergiants are relatively rare. Only a few stars become hypergiants, and they don't last very long (only a few million years). Probably a few in every major galaxy.
12.... age doesnt change on other planets, nor does mass.
The sun is a star. And planets within its gravitational reach orbit it.
no its doesnt have any moons. because its to hot for it but they consider the planets to be the suns moons
none the sun doesnt circle the planet planets circle the sun!!!
Hypergiants are stars with a tremendous mass and luminosity, showing signs of a very high rate of mass loss. Hypergiants are very luminous stars, up to millions of solar luminosities, and have temperatures varying widely between 3,500 Kelvin and 35,000 Kelvin.Because of their high masses, the lifetime of a hypergiant is very short, only a few million years compared to around 10 billion years for stars like the Sun.See link for a pictorial representation of our Sun compared to the largest known hypergiant.
because the gravity keeps the giants planets' gases from escaping.

Red giants, red supergiants and red hypergiants.
