Question

The planet having largest diameter is
A. Jupiter
B. Saturn
C. Pluto
D. Mars

Answer 1

Hint: There are eight planets in our solar system namely Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune and four terrestrial planets namely Mercury, Venus, Earth and Mars. There are two gas giants namely Jupiter,Saturn and two ice giants namely Uranus and Neptune.

Complete step by step answer:
Jupiter edges out all the other planets in both mass and volume. It is considered as the biggest planet in our solar system. The mass of Jupiter is over 300 times that of earth, and its diameter is about 11 times the diameter of earth at 140,000km. It takes 10 hours in order to complete one revolution with a rotational velocity of 12.6km/s. Magnetic field in Jupiter is 14 times stronger than Earth’s magnetic field and 67 moons revolving around it.

So, the correct answer is “Option A”.

Additional Information:
Saturn: Saturn is the sixth planet from the Sun and after Jupiter, the second largest in the solar system. It is a gas giant with a radius of around nine times the Earth’s average. It has one eighth of the Earth’s average density, nevertheless, it is over 95 times more massive with its greater volume. Its mesmerising rings aren’t solid and are made up of ice, dust and rock. Because it is made up of gas, Saturn can float on water.

Mars: It is the fourth planet which is away from the Sun and considered to be the second smallest planet in the solar system, larger than Mercury alone. It is also called the Red planet. It is red in color because of rusty iron in the ground. Mars has seasons, polar ice caps, volcanoes, canyons, and weather similar to the planet Earth. It has a very thin layer of atmosphere made up of carbon-di-oxide, nitrogen and argon.

Pluto:In the Kuiper belt, Pluto is a small planet, a ring of bodies outside Neptune’s orbit. It was the first to be discovered and the largest Kuiper belt object. It was declared to be the Sun’s ninth planet. The status of Pluto was downgraded to that of a small planet by the International Astronomical Union (IAU) because it did not meet the three requirements that the IAU uses to describe a full-sized planet.

Note:
Jupiter is considered to be the fastest spinning planet in our solar system. It has four significant moons namely lo, Europa, Ganymede and Callisto.
They are collectively known as the Galilean moons.
It takes 10 hours in order to complete one revolution with a rotational velocity of 12.6km/s.
