Is Venus the densest planet?
In fact, that turns out to be the case, except for one giant surprise: Mercury, Venus, and the Earth are the three densest worlds in the Solar System. Mars is the next most-dense object, followed by Jupiter's innermost large moon, Io, then by Earth's moon, and then by Jupiter's second large moon, Europa.
Which planet is the densest in our Solar System quizlet?
Which is the densest planet in the solar system? Venus.
What is the densest and largest planet in the Solar System?
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 the Earth is the densest planet in the Solar System?
Earth is closer to that limit than anything else in our Solar System, and the combination of its relatively dense composition and its enormous self-gravity, as we're 18 times as massive as Mercury, places us alone as the densest object in our Solar System.
Is Mercury the 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 Neptune the densest planet?
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.
What is the largest planet in the solar system quizlet?
Jupiter is the largest planet in our Solar System.
Is Venus a Jovian?
With the exception of Pluto, planets in our solar system are classified as either terrestrial (Earth-like) or Jovian (Jupiter-like) planets. Terrestrial planets include Mercury, Venus, Earth, and Mars.
What’s the densest thing on Earth?
element osmium At the modest temperatures and pressures of Earth's surface, the densest known material is the metallic element osmium, which packs 22 grams into 1 cubic centimetre, or more than 100 grams into a teaspoonful. Even osmium is full of fluff, however, in the form of electron clouds that separate the dense atomic nuclei.
Is Mercury or Earth more dense?
Earth is the densest planet in our Solar System, but Mercury's uncompressed density is even higher than the Earth's. Q: Which is the least dense planet? The least dense planet in our Solar System is Saturn.
What is the second densest planet?
Mercury Mercury is the second densest planet of our solar system, second only to Earth.
What planet is Uranus?
Uranus is the seventh planet from the Sun, and has the third-largest diameter in our solar system. It was the first planet found with the aid of a telescope, Uranus was discovered in 1781 by astronomer William Herschel, although he originally thought it was either a comet or a star.
Which planet has the second largest moon in the solar system quizlet?
Titan Moon orbits Saturn and is the second largest moon with a diameter of 5,150 km.
Why is Pluto not a planet?
Answer. The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”
Who is Roman god named after?
Venus was named after the Roman goddess of love and beauty. Mars was the Roman god of War. Jupiter was the king of the Roman gods, and Saturn was the Roman god of agriculture. Uranus was named after an ancient Greek king of the gods.
How dense is GOLD?
19.3 g/cc Different materials have different densities. For example, the mass density of gold is 19.3 g/cc, lead is 11.4 g/cc, copper is 9.0 g/cc, aluminum is 2.7 g/cc, water is 1.0 g/cc (1g/cc = 1 gram per cubic centimeter). If we want the density in English units we could use 11.1 oz/cubic inch as the density of gold.
How dense is a black hole?
There is a rough analogy between a black hole and an atom. In both cases, the mass is concentrated in a tiny region at the center, but the "size" of the object is much bigger. The radius of a nucleus is (r = A1/3 x 1.7 x 10-13 cm), where A is the mass number of the nucleus….Density of Black Holes.
| Material | ρ / g/cm3 |
|---|---|
| Black hole | 4 × 1014 |

Is Jupiter more dense than Earth?
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.
What is the third densest planet?
Planetary Densities
| Planet | Average Density (gm/cm3) | Required Mass for 70 cm3 (gm) |
|---|---|---|
| Venus | 5.2 | 364.0 |
| Earth | 5.5 | 385.0 |
| Mars | 3.9 | 273.0 |
| Jupiter | 1.3 | 91.0 |
Which planet is called green planet?
Uranus Physical characteristics. Uranus is blue-green in color, as a result of the methane in its mostly hydrogen-helium atmosphere.
What is the most interesting planet?
The Latest. Adorned with thousands of beautiful ringlets, Saturn is unique among the planets. It is not the only planet to have rings – made of chunks of ice and rock – but none are as spectacular or as complicated as Saturn's. Like fellow gas giant Jupiter, Saturn is a massive ball made mostly of hydrogen and helium.
Is Jupiter a gas giant yes or no?
Jupiter is called a gas giant planet. Its atmosphere is made up of mostly hydrogen gas and helium gas, like the sun. The planet is covered in thick red, brown, yellow and white clouds.
Which planet stays the closest to Earth the longest?
Mercury Although Venus is the planet that comes closest to Earth as it sweeps by on its orbit, Mercury stays the closest to Earth the longest, according to a commentary published Tuesday (March 12) in the magazine Physics Today.
Are there 6 dwarf planets?
Currently, there are six dwarf planets officially designated by the IAU: Pluto, Ceres, Eris, Makemake, Haumea, and 2015 RR245, discovered in July.
How was Pluto destroyed?
FYI: Pluto is not destroyed, it is no longer considered a planet as per the definitions of astronomy, and now it comes under the category of "Dwarf Planet". Actually, the farthest planet of the solar system Pluto has neither died nor has been destroyed.
Who was the ugliest god?
Hephaestus Hephaestus. Hephaestus is the son of Zeus and Hera. Sometimes it is said that Hera alone produced him and that he has no father. He is the only god to be physically ugly.
Who named the Earth?
All of the planets, except for Earth, were named after Greek and Roman gods and godesses. The name Earth is an English/German name which simply means the ground. It comes from the Old English words 'eor(th)e' and 'ertha'. In German it is 'erde'.
What is the heaviest metal?
osmium The Heaviest Metal. The heaviest metal is osmium, which has, bulk for bulk, nearly twice the weight of lead. The specific gravity of gold is about 19 1/4, while that of osmium is almost 22 1/2.
How dense are diamonds?
3.514 grams per cubic centimeter It is a strong, rigid three-dimensional structure that results in an infinite network of atoms. This accounts for diamond's hardness, extraordinary strength and durability and gives diamond a higher density than graphite (3.514 grams per cubic centimeter).
Do wormholes exist?
Wormholes are shortcuts in spacetime, popular with science fiction authors and movie directors. They've never been seen, but according to Einstein's general theory of relativity, they might exist.
