Question

Which planet is the biggest in size in the solar system__
a. Mercury
b. Venus
c. Neptun
d. Jupiter

Answer 1

Hint:
The Solar System, either directly or indirectly, is the Sun's gravitationally bound system and the objects that orbit it. Of the objects directly orbiting the Sun, the eight planets with the dwarf planets and small Solar System bodies.

Complete answer:
Our solar system has eight planets. Among them, Jupiter is our solar system's largest planet. It is the highest in volume as well as mass. Jupiter's mass is 300 times that of Earth's. Its diameter is 140,000 kilometres, nearly 11 times the diameter of the Earth. Jupiter is 2.5 times as massive as the total mass of the rest of the solar system's planets. Given its bulk size, it has a rotation time of just 10 hours.

Jupiter is the Sun's fifth planet and the largest planet in the Solar System. It is a gas giant, one-thousandth of the Sun's mass, but two-and-a-half times that of all the other planets combined in the Solar System. Jupiter is one of the brightest objects visible in the night sky to the naked eye, and long before recorded history, it has been known to ancient civilizations. Jupiter can be bright enough for its reflected light to cast visible shadows as viewed from Earth and is the third brightest natural object in the night sky after the Moon and Venus on average.

Jupiter consists mainly of hydrogen, with helium being a quarter of its mass, while helium consists of just about a tenth of the number of molecules. It may also have a heavier rocky centre of elements, but Jupiter lacks a well-defined solid surface like the other giant planets.

Hence, the correct answer is option D.

Note:
Jupiter has 79 known moons, including the four major Galilean moons that Galileo Galilei discovered in 1610. The largest of these, Ganymede, is larger in diameter than that of the planet Mercury.
