which is the biggest planet?

Answer 1

Jupiter is the biggest in our solar system, theres probably bigger in the rest of the universe but not by to much, if jupiter were a bit bigger it's own gravity would be enough to induce fusion and make it a star

Answer 2

Jupiter is the largest planet in the solar system and it is the fifth planet from the Sun. Since all the planets are named after gods, we have to tell you which one Jupiter is. Jupiter is from Roman mythology and is the equivalent to Zeus from Greek mythology.

Jupiter - What It's All About
Jupiter is a planet made mostly of gases. It is part of a group sometimes called the Jovian planets (gas giants). This planet has no solid surface. Jupiter is sometimes called a failed star because it is made up entirely of gases. It would, however, have to be much larger in size than it is today to be qualified as a star. Jupiter has about 60 moons but the four largest moons were discovered by Galileo Galilei in 1610. The moons, Io, Europa, Ganymede and Callisto were discovered using a telescope and are now called the Galilean moons. This was also the first observation of moons other than Earth's.

Europa is one of Jupiter's 60 moons.

There is one feature of Jupiter that is very distinct. Jupiter has something called the Great Red Spot. While this feature looks something like a big ketchup smudge on the planet, it is actually a very, very big hurricane. The spot was first discovered by Cassini (an Italian astronomer) in 1665. That means the storm has lasted hundreds of years. Even from Earth, you can see the spot using a telescope. The storm is bigger than three Earths put together. Scary, huh?

Jupiter - Fun Facts
# Jupiter is the fourth brightest object in the sky.
# Jupiter is 2.5 times bigger than all the planets combined.
# This giant is 318 times the size of Earth.
# If you weigh a hundred pounds on Earth, you would weigh 236 pounds on Jupiter.
# A day on Jupiter is less than 11 hours.
# It takes Jupiter about 12 Earth years to go around the Sun.

Answer 3

Jupiter is the fifth planet from the Sun and is the largest one in the solar system. If Jupiter were hollow, more than one thousand Earths could fit inside. It also contains more matter than all of the other planets combined. It has a mass of 1.9 x 1027 kg and is 142,800 kilometers (88,736 miles) across the equator. Jupiter possesses 28 known satellites, four of which - Callisto, Europa, Ganymede and Io - were observed by Galileo as long ago as 1610. Another 12 satellites have been recently discovered and given provisional designators until they are officially confirmed and named. There is a ring system, but it is very faint and is totally invisible from the Earth. (The rings were discovered in 1979 by Voyager 1.) The atmosphere is very deep, perhaps comprising the whole planet, and is somewhat like the Sun. It is composed mainly of hydrogen and helium, with small amounts of methane, ammonia, water vapor and other compounds. At great depths within Jupiter, the pressure is so great that the hydrogen atoms are broken up and the electrons are freed so that the resulting atoms consist of bare protons. This produces a state in which the hydrogen becomes metallic.
Colorful latitudinal bands, atmospheric clouds and storms illustrate Jupiter's dynamic weather systems. The cloud patterns change within hours or days. The Great Red Spot is a complex storm moving in a counter-clockwise direction. At the outer edge, material appears to rotate in four to six days; near the center, motions are small and nearly random in direction. An array of other smaller storms and eddies can be found through out the banded clouds.

Auroral emissions, similar to Earth's northern lights, were observed in the polar regions of Jupiter. The auroral emissions appear to be related to material from Io that spirals along magnetic field lines to fall into Jupiter's atmosphere. Cloud-top lightning bolts, similar to superbolts in Earth's high atmosphere, were also observed.

Answer 6

Inside the solar system it is Jupiter. Currently the largest planet discovered outside of our solar system, also know as Extrasolar planets, is HAT-P-1b which is estimated to be close to 1.5 times larger then Jupiter. It is located in the Lacerta constellations.

Answer 7

Answer 8

in our solar system jupiter is the biggest planet

Answer 9

biggest planet is known to be jupiter

Answer 10

In our solar system Jupiter is 'considered' the largest planet. Beyond it we don't yet know.
