SOLAR SYSTEM

Detailed explanation-1: -The remaining objects of the Solar System (including the four terrestrial planets, the dwarf planets, moons, asteroids, and comets) together comprise less than 0.002% of the Solar System’s total mass. The Sun is composed of roughly 98% hydrogen and helium, as are Jupiter and Saturn.

Detailed explanation-2: -The major part of the remaining mass will be in the planets like Jupiter, Saturn, Uranus, and Neptune. Where P is the Orbital Period, M is the mass of the planet and G is the gravitational constant. Thus the percentage of the solar system’s mass in the sun is 99.8% and we calculate it by using the above formula.

Detailed explanation-3: -Venus is the second planet from the Sun and is Earth’s closest planetary neighbor. It’s one of the four inner, terrestrial (or rocky) planets, and it’s often called Earth’s twin because it’s similar in size and density.

Detailed explanation-4: -As the star for nine planets, a multitude of asteroids, comets and other celestial objects, the Sun contains more than 99 percent of the entire mass in the solar system. For more information, visit NASA’s Sun Earth Connection site.

Detailed explanation-5: -The Sun is a yellow dwarf star at the center of our solar system. Earth and all other objects in our solar system orbit around the Sun due to gravity – the Sun contains over 98% of all mass in the solar system and so exerts a strong gravitational pull.
