WebTRAPPIST-1, also known as 2MASS J23062928-0502285, is an ultra-cool red dwarf star that is slightly larger, although much more massiver than the planet Jupiter. It is located 39.6 light-years (12.1 pc) from the Sun in the constellation Aquarius. Seven temperate terrestrial planets have been detected orbiting the star, a larger number than detected in any other … WebDec 18, 2024 · Luminosity is an absolute measure of radiated electromagnetic power (light), the radiant power emitted by a light-emitting object over time. In astronomy, luminosity is the total amount of electromagnetic energy emitted per unit of time by a star, galaxy, or other astronomical object.

WebThe Stefan-Boltzmann equation then gives the energy flux emitted at the sun’s surface. S S = (5.67 × 10 –8 W·m –2 ·K –4 ) (5800 K) 4 = 63 × 10 6 W·m –2. The surface area of a sphere with a radius r is 4πr 2. If r S is the radius of the Sun, the total energy it emits is S S 4πr s2. As the radiation is emitted from this spherical ...
