Which two planets have the least density?

Which two planets have the least density?

Jupiter is the largest planet in the solar system, but it’s Saturn—the solar system’s second largest planet—that takes the prize for least dense.

Is Earth the least dense planet?

The least dense planet in the Solar System is Saturn, which has an average density of only 687 kg/m3 (42.8 lb/cu ft). By comparison, Earth’s average density is 5,513 kg/m3 (344 lb/cu ft).

Which planet has lowest gravity?

Planet	Diameter (Compared to Earth)	Gravitational Field Strength
Mercury	0.4	4 N/kg
Venus	0.9	9 N/kg
Earth	1	10 N/kg
Mars	0.5	4 N/kg

Is Uranus the least dense planet?

Uranus is slightly larger in diameter than its neighbor Neptune, yet smaller in mass. It is the second least dense planet; Saturn is the least dense of all.

Which planet has most density?

Mercury and Earth are the densest planets in the Solar System (Figure 13) with densities similar to the iron-rich mineral haematite. Saturn, the least dense planet in the Solar System on the other hand, has a density lower than that of water.

Is Uranus less dense than Earth?

Uranus Internal Structure: Uranus’s mass is roughly 14.5 times that of Earth, making it the least massive of the giant planets. Its diameter is slightly larger than Neptune’s at roughly four times that of Earth. A resulting density of 1.27 g/cm3 makes Uranus the second least dense planet, after Saturn.

Is Neptune the least dense planet?

Neptune is one of two ice giants in the outer solar system (the other is Uranus). Most (80% or more) of the planet’s mass is made up of a hot dense fluid of “icy” materials – water, methane, and ammonia – above a small, rocky core. Of the giant planets, Neptune is the densest.

Is Jupiter less dense than Earth?

Density, mass and volume Although it is significantly more massive than Earth, it is only a fifth as dense, at 1,326 kg/m3, because it is made of gas rather than rock. The volume of Jupiter is 1,431,281,810,739,360 cubic kilometers, 1,321 times that of Earth.

Which planet gravity is highest?

Jupiter has the highest amount of gravity in our solar system. By India Today Web Desk: Jupiter is the largest in our Solar System, meaning it also has the highest gravity. You would weigh two and a half times on Jupiter than what you would on Earth.

Which is the lightest planet in the world?

Saturn is the second biggest planet in our solar system. Similar to Jupiter it has over 60 moons and is made up of different gases. Even though it is a gas giant, it is also the lightest planet. Saturn is so light that it would float in water, if there was an ocean big enough.

Which planet has no atmosphere?

Among all the planets, Mercury is the one with no atmosphere.

Which planet is the hottest?

Venus’ thick atmosphere traps heat creating a runaway greenhouse effect – making it the hottest planet in our solar system with surface temperatures hot enough to melt lead. The greenhouse effect makes Venus roughly 700°F (390°C) hotter than it would be without a greenhouse effect.

Why is Uranus less dense?

Density, mass and volume The density of Uranus is 1.27 grams per cubic centimeter, making it the second least dense planet in the solar system. Its low density indicates that it is predominantly composed of ice rather than gas.

Which planet has highest density MCQS?

Explanation: Planet Earth in the Solar System has the highest density.

Which planet can float on water?

Saturn is very large and is the second largest planet in the Solar System. However, it is made up mostly of gas and is less dense than water. Since it is lighter than water, it can float on water. Q.

Why is Mars density so low?

Density of Mars: The planet’s overall density is lower than that of Earth’s, estimated at 3.933 g/cm³, and this density increases the closer one gets to the core. Like Earth, this is due to the fact that the core is composed of iron and nickel, while the mantle is made up of silicate materials.

Which planet is the least dense and most dense?

Saturn has the lowest density of all the planets in our solar system. Infact, its density is less than that of water.

What is the second least dense planet?

With a mean density of 1.27 g/cm3, Uranus is the second-least dense of the gas giants, after Saturn. Its slightly higher density is due to its composition, which consists primarily of various volatile ices – such as water, ammonia, and methane – in addition to gases like hydrogen and helium.

Which two 2 planets have the least number of moons?

Of the terrestrial (rocky) planets of the inner solar system, neither Mercury nor Venus have any moons at all, Earth has one and Mars has its two small moons.

Is Neptune the least dense planet?

Neptune is one of two ice giants in the outer solar system (the other is Uranus). Most (80% or more) of the planet’s mass is made up of a hot dense fluid of “icy” materials – water, methane, and ammonia – above a small, rocky core. Of the giant planets, Neptune is the densest.
