Which two planet are gas gaints?

Answer 1

Jupiter. Jupiter's total mass is approximately 1,900,000,000,000,000,000,000,000,000 kilos, which is 318 times the Earth's mass and equivalent to 2½ times all the other planets put together. Jupiter's diameter is 143,000 kilometers which is 11.2 times the Earth's diameter. The volume of Jupiter is 1,430,000,000,000,000 cubic kilometers which is 1320 times Earth's volume.

Answer 2

A solar system consists of one (or more) stars (or suns), and various orbiting bodies (e.g. planets, moons, meteors, comets, dust, gas).

A galaxy, on the other hand, is much larger in scale, and consists millions or billions of stars, interstellar dust and gas, and dark matter. Our own solar system is a tiny part of the Milky Way galaxy; it has a radius of about 7,500,000,000 kilometers, whereas the Milky Way has a radius of about 1,000,000,000,000,000,000. In order words: the Solar System is about 0.0032% of the size of the Milky Way.

If, on the other hand, you were asking what the biggest galaxy in the the universe, then the current answer is Galaxy ACT-CL J0102-4915 (also known as 'El Gordo'). This galactic cluster is about 7 billion light years from Earth and is over 3,000 times as massive as the Milky Way.

Answer 3

Planets are divided into 2 main catagories. Gas giant planets and terrestrial planets. Terrestrial planets are mostly rock/ice with relatively thin atmospheres.

Gas giants are mostly atmosphere.

The 4 gas giants in the solar system are :-

• Jupiter
• Saturn
• Uranus
• Neptune

Uranus and Neptune are sometimes classified as ice giants rather than gas giants as the contain much higher concentrations of water, methane etc than Jupiter and Saturn but they are still technically gas giants.

Answer 4

I suppose if you're looking for a galaxy type which is the brightest in visible light, that would be the quasar. These are incredibly distant galaxies with super-massive black holes at the centre. Before matter falls into the black hole, a massive amount of energy is given off. We see this as visible light. Quasars are some of the brightest objects in the universe.

Answer 5

There are no galaxies in the solar system.

Our solar system consists of a cloud of dust particles circling around one star called "the sun".

We live on one of those specks of dust and call it "earth". The next star nearest to us is

about 25,865,000,000,000 miles away. That star and "the sun" are two stars out of

something between 200-400 billion stars that make up one galaxy ... the one we live in.

The next nearest galaxy is about 14,695,700,000,000,000,000 miles away.

Answer 6

Not much is known yet about solar systems (or stellar systems) outside our own. Planets have been found around a few thousand stars - out of the estimated 10 to the power 22 in the observable Universe.You would also have to clarify what you mean by "biggest". Do you mean:

* Largest star (in diameter)?

* Largest star (in mass)?

* Largest number of planets above a certain mass or size limit (the limit would have to be specified)?

* Largest total mass of planets?

* Largest diameter of orbit, of the outermost planet?

* Or perhaps some other criterion.

Whichever criterion you choose - you won't get a very reliable answer yet, based on the limited amount of observational evidence.

Answer 7

Jupiter and Saturn are considered gas giants because they are primarily composed of hydrogen and helium, with no solid surface.

Answer 8

Neptune and Uranus

Answer 9

Elliptical galaxies tend to be the biggest and oldest.

Answer 10

There are four in our solar system; Jupiter, Saturn, Uranus and Neptune.
