SOLAR SYSTEM

Detailed explanation-1: -[/caption]The large-scale structure of the Universe is made up of voids and filaments, that can be broken down into superclusters, clusters, galaxy groups, and subsequently into galaxies.

Detailed explanation-2: -If you were to order the planets by size from smallest to largest they would be Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn and Jupiter. Jupiter and Saturn are sometimes called the gas giants, whereas the more distant Uranus and Neptune have been nicknamed the ice giants.

Detailed explanation-3: -The radius of the observable universe is therefore estimated to be about 46.5 billion light-years and its diameter about 28.5 gigaparsecs (93 billion light-years, or 8.8×1026 metres or 2.89×1027 feet), which equals 880 yottametres.

Detailed explanation-4: -Descending order means the largest or last in the order will appear at the top of the list: For numbers or amounts, the sort is largest to smallest.

Detailed explanation-5: -Size is the biggest distinction between the solar system, galaxy, and Universe. The smallest is the Solar System. The Solar System consists of the Sun, and everything bound to it by gravity: planets, moons, asteroids, comets, and meteoroids. At the center of the Solar System is the Sun, which is a star.
