How much is luminosity
WebThe lifetimes of main sequence stars therefore range from a million years for a 40 solar mass O-type star, to 560 billion years for a 0.2 solar mass M-type star. Given that the Universe is only 13.7 billion years old, these long main sequence lifetimes for M-type stars mean that every M star that has ever been created is still on the main sequence! WebMar 4, 2015 · It also has its own luminosity (predominantly in the infrared). A quick calculation: The solar constant (flux at 1 au) is about 1370 W/m 2. Jupiter is situated about 5.2 au from the Sun (it varies by about +/- 5%) and …
