The temperature of a star depends on the color and size. The hottest stars is the blue hypergiant stars, which has a mass more than 100 times bigger than our sun. (1000 Kelvin = 726oC = 1340oF)
Rigel (17 times the mass of the Sun, 11,000 Kelvin), Bellatrix (21,500) are two examples of blue stars. The star thought to be the hottest in the universe is called Eta Carinae, and has a surface temperature at 36,000-40,000 Kelvin.
On the other side of the scale, NASA may have found a class of stars called brown dwarfs. Measurements has shown that the surface temperature of the brown dwarf (locates 75 light years from the Earth) is about 300 Kelvin.
The more common "cold" star class is the red dwarfs, which have a surface temperature at less than 4,000 Kelvin.
Our Sun has a surface temperature at about 6,000 Kelvin.
Compared to the other stars in the universe, our sun is not very very hot. There are a bunch of other, much warmer stars. Even though the Sun isn't hot compared to many other stars, I wouldn't recommend travelling there.
