The Sun's Gravity is Literally Everything #astronomy #shorts

[00:00:00]What if I told you our sun weighs over a million trillion trillion kilograms?

[00:00:05]That's 1.99 * 10 to the 30th power.

[00:00:08]Imagine squeezing 333,000 Earths into one blazing ball of fire.

[00:00:14]The sun is so massive, it makes up nearly 99.86% of all the mass in our solar system. But how do we know this? Scientists measure the sun's gravity by watching how it keeps planets like Earth in orbit, then use Newton's laws to calculate its mass.

[00:00:30]Here's something wild. Every second, the sun loses about 4 million kilograms as it turns mass into energy. Yet, compared to its total weight, that's barely a scratch. It'll keep shining for another 5 billion years. The sun's incredible heft is what holds our planets, comets, and asteroids in place, giving us warmth, seasons, and life.

[00:00:57]That's the power of our star, anchoring everything we know.
