The Largest Object In The Solar System
The largest object in the Solar System is the Sun. Its diameter is about 864,400 miles, which is about 109 times the diameter of Earth. Its mass is about 333,000 times the mass of Earth, and it makes up 99.86% of the total mass of the Solar System. The Sun is a star composed mainly of hydrogen and helium, and it is the source of life on Earth. Its immense gravity holds the Solar System together, while its intense radiation powers the planets and asteroids in their orbits. It also provides the heat and light necessary for life on Earth.

Explanation of how size is determined
When it comes to determining the size of an object, the most important factor to consider is the object’s mass. Mass is determined by the amount of matter that an object contains and is measured in kilograms. This is why objects with larger masses tend to be larger in size. In the Solar System, the largest object by mass is the Sun, which contains around 99.86% of the total mass of the Solar System.
Interestingly, the Sun is not the largest object in the Solar System. That title belongs to the planet Jupiter, which is the fifth planet from the Sun and the largest planet in the Solar System. Although Jupiter is much less massive than the Sun, its immense size gives it the title of the largest object in the Solar System.

Jupiter’s diameter is around 142,984 kilometers, making it 11 times larger than Earth. It is also the fifth brightest object in the night sky, just after the Sun, Moon, Venus, and Mars. Jupiter’s large size is due to its enormous gravitational pull, which allows it to draw in vast amounts of gas and other materials from the Solar System. This allows it to form a large, gaseous atmosphere that is composed of hydrogen and helium.
In addition to Jupiter, the other outer planets in the Solar System (Uranus, Neptune, and Saturn) are also much larger than the inner planets (Mercury, Venus, Earth, and Mars). This is because the outer planets are composed mostly of gas, rather than solid rock and metal, allowing them to grow much larger than the inner planets.
The size of an object in the Solar System is determined by its mass, as well as its composition. Objects with large masses tend to be larger in size, and objects composed mostly of gas tend to be much larger than those composed of solid rock and metal. The largest object in the Solar System is Jupiter, which is 11 times larger than Earth due to its enormous gravitational pull.
Conclusion
The Largest Object In The Solar System is the Sun. It is huge and so bright it’s hard to look at it with your eyes. It’s also the source of all the planets’ and moons’ orbits.
