Regulus is 0.46 degree from the ecliptic, the closest of the bright stars, and is regularly occulted by the Moon. Occultations by the planets Mercury and Venus are possible but rare, as are occultations by asteroids. The last occultation of Regulus by a planet was on July 7, 1959, by Venus.
Surface temperature. Also, if a star has the same radius as the sun but a higher surface temperature, the hotter star exceeds the sun in luminosity. The sunâs surface temperature is somewhere around 5800 Kelvin (9980 o Fahrenheit).Thatâs 5800 degrees above absolute zero, the coldest temperature possible anywhere in the universe.etâs presume a star has the same surface temperature as the sun, but sports a larger radius. In that scenario, the star with the larger radius claims the greater luminosity. In the example below, weâll say the starâs radius is 4 solar (4 times the sunâs radius) but has the same surface temperature as our sun.
