UY Scuti is HUGE, if it replaced the sun it would extend out of Saturn's orbit.
Observations of the largest known star, currently UY Scuti, indicate it has no companion; so it is almost certainly not being eaten by a black hole, so to speak.
For a long times, it was considered to be VY Canis Majoris, but new studies have reduced its size. The present record is held by UY Scuti at 1708 times the diameter of the Sun. That works out to about 2,250,000,000km.
A hypergiant which has tremendous mass and luminosity, showing signs of a very high rate of mass loss.Candidates are VY Canis Majoris the largest known star, Eta Carinae and RW Cephei.
Some stars are actually bigger than others, and some are closer to us, so appear bigger. The biggest star is UY Scuti, which is 1708 times bigger than the sun. It is 7800 light years away. The closest is Alpha Centauri, at 4.5 light years away. Note: nearly all stars are so far away that they still appear as just points of light, even in large telescopes. The angular size of some stars can be measured using "interferometry".
UY Scuti The biggest known star is UY Scuti, about 1,700 times larger than the sun.

UY Scuti is bigger than Westerlund 1-26. It has a radius of 1,708 while Westerlund has a radius of 1,530.

No. Currently UY Scuti is the star estimated to be the biggest, but we are not very sure of their size; beside UY Scuti, VY Canis Majoris and a few other stars are also larger than Betelgeuse.
The largest known star now is UY Scuti with a diameter 2,375,828,000 km. UY Scuti has the radius of 1,516-1,900 solar radii, with the median radius of 1,708 solar radii, or approximately 7.94 astronomical Units.

The largest star discovered so far is the UY Scuti red supergiant. It is approximately 1,708 solar radii, where one solar radii equals the radius of the Sun in our solar system.
