Which planet is the densest planet in the Solar System?
Earth
Earth is the fourth smallest of the planets—though in terms of the rocky planets, it’s the largest—but it’s the most dense. 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.
Why is Earth considered the densest planet in the Solar System?
Earth is the densest planet for two reasons: it is made of dense material, and it is heavy. Both points need a bit more elaboration. Compared to a gas giant, Earth is dense! The average chunk of Earth (which is the average value of crust, mantle, all that) weighs over 5.5 grams/cm3.
What is the densest planet besides Earth?
Mercury
However, if the effects of gravitational compression – in which the effects of gravity reduce the size of an object and increases its density – then Mercury is in fact more dense than Earth, with an uncompressed density of 5.3 g/cm³ compared to Earth’s 4.4 g/cm³.B
Is Earth the second densest planet?
Structure. Mercury is the second densest planet, after Earth. It has a large metallic core with a radius of about 1,289 miles (2,074 kilometers), about 85 percent of the planet’s radius.
Is Earth the 4th largest planet?
The Latest. While Earth is only the fifth largest planet in the solar system, it is the only world in our solar system with liquid water on the surface. Just slightly larger than nearby Venus, Earth is the biggest of the four planets closest to the Sun, all of which are made of rock and metal.
Which is the densest planet in the solar system quizlet?
Earth The third planet from the Sun and the densest planet in the solar system. Earth is a terrestrial or inner planet consisting of a thin outer crust, an intermediate mantle, and a dense inner core.
Why is the Earth more dense than the Sun?
Water is much less dense than iron, hence an average is needed for ease of use. Earth is the most dense planet in the Solar System; however, if gravitational compression where factored out, the second most dense planet, Mercury, would be more dense….Density of the Earth.
| Mercury | 5.43 g/cm3 |
|---|---|
| Neptune | 1.638 g/cm3 |
| The Sun | 1.408 g/cm3 |
What is Earth’s density?
5.51 g/cm³
Earth/Density
Which planet has highest 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.
Which planet in the solar system is least dense quizlet?
Which planet has the lowest density? Neptune is the slowest planet.
Which planet has the lowest density in our solar system?
Saturn
Since it is lighter than water, it can float on water. None of the other planets in our Solar System can do this because they have a higher density than water. Saturn has the lowest density of all the planets, which means that it does not weigh as much for its size as the other planets do.
