The cosmos is replete with numerous celestial bodies – planets, moons, asteroids, and comets, some of which are yet to be discovered. Despite the vast unknown, we have deduced the mass of our Solar System with remarkable precision.
Dwarfing all else, the Sun holds an astounding 99.85 percent of the total mass of the Solar System. To comprehend this astronomical figure, picture a 2 followed by thirty zeros! That's almost two quintillion kilograms, the staggering weight of the Sun.
Following the Sun, the eight planets in our system constitute a mere 0.135% of the total mass. Our home, Earth, with a mass of approximately 6x10^24 kg, might be the heaviest terrestrial planet, but it pales in comparison to the gargantuan gas giants. Jupiter, the heaviest of all planets, boasts a mass 318 times that of Earth.
Beyond the planets, the Solar System teems with smaller bodies. From nearly 2 million asteroids greater than one kilometer in diameter in the Main Belt to an untold number of smaller entities, the count is virtually incalculable.
Add to this the interplanetary medium, a residual dust from the system's formation, and we encounter a myriad of components that contribute less than 0.015 percent to the total mass.
In sum, the Solar System is a dynamic, complex entity, brimming with celestial bodies of varying sizes and weights, each contributing to the grand cosmic scale in its unique way.
