Why does Earth get more energy from the sun than from all the other stars in the universe combined?
BTS ARMY
the sun (a star) is a heck of a lot closer
the energy follows the inverse-square law
the energy is inversely proportional to the square of the distance
Hehe was this on a test u were taking?😂😉 same
not me being on the same test lmaoo
you love bts?
Omg I have this one my dumb test
Omg im not the only BTS ARMY here!! Bangtan Forever!!
Kim Namjoon!
Kim Soekjin!
Min Yoongi!
Jung Hoseok!
Park Jimin!
Kim Taeyoung!
Jeon Jungkook!
BTS!
The Sun is much closer than the other stars
The sum total energy received from all of the stars other than the Sun is infinitesimally little. The earth receives more of the Sun’s energy reflected by the Moon than from the stars.
To understand why Earth receives more energy from the Sun than from all the other stars in the universe combined, we need to explore two main factors: distance and luminosity.
1. Distance: The Sun is relatively close to Earth compared to other stars in the universe. The distance between the Sun and Earth is about 93 million miles (or 150 million kilometers), which places the Sun in our own solar system. In contrast, the vast majority of stars in the universe are located light-years away, making them much farther from Earth.
2. Luminosity: The Sun is an average-sized, main-sequence star. It is neither exceptionally large nor exceptionally small. However, it is relatively more luminous compared to typical stars. Luminosity refers to the total amount of energy a star emits per second. The Sun's luminosity is estimated to be around 3.8 x 10^26 watts, which is quite high.
Combining these factors, the Sun appears much larger and brighter in our sky than any other star, simply because of its proximity. When we consider the vast number of stars in the universe, the collective energy they emit is indeed enormous. However, due to the vast distances involved, the amount of energy Earth receives from all other stars is significantly smaller when compared to the Sun's energy.
Now, let's quantify this difference. The average luminosity of all stars in the Milky Way galaxy (our galaxy) is estimated to be around 10^37 watts, whereas the Sun's luminosity is about 10^26 watts. Considering that the Milky Way contains hundreds of billions of stars, the total energy from all the stars is still less than what the Sun alone provides to Earth.
In summary, Earth receives more energy from the Sun than from all other stars combined due to the Sun's relatively close distance and its higher luminosity compared to the majority of stars in the universe.
