Since Uranus and Neptune are smaller and have bigger orbits, it was harder for them to collect hydrogen and helium as efficiently as Jupiter and Saturn. This likely explains why they are smaller than those two planets.
Why are Jupiter and Saturn so much larger?
Have you ever wondered why Jupiter and Saturn are very close in size, but Jupiter’s average density is almost twice Saturn’s? … Jupiter continued to collect hydrogen and helium in its atmosphere, increasing its mass and compressing its interior until its average density was twice Saturn’s.
What caused Jupiter and Saturn to be the largest planets in the Solar System?
They are all small with solid, rocky surfaces. Meanwhile, materials we are used to seeing as ice, liquid, or gas settled in the outer regions of the young solar system. Gravity pulled these materials together, and that is where we find gas giants Jupiter and Saturn, and the ice giants Uranus and Neptune.
Why is Jupiter so much larger than the other planets?
Jupiter is so big because it is the oldest planet in our Solar System. It formed around one million years after the Solar System. … The giant proportions of Jupiter were meant to be, and any planet might have been in the same position as Jupiter if it formed earlier than it.
Why is Saturn so large?
Saturn is a gas giant made up mostly of hydrogen and helium. … The planet’s high-speed spin causes Saturn to bulge at its equator and flatten at its poles. The planet is around 75,000 miles (120,000 kilometers) across at its equator, and 68,000 miles (109,000 km) from pole to pole.
Is Uranus bigger than Saturn?
Saturn is the second largest planet in our Solar System. It has a diameter of 120,536 km across the equator, and a surface area of 4.27 x 1010 km2. With a volume of 8.27 x 1014 km3, Saturn can hold 764 Earths inside. Uranus has a diameter of 51,118 km and a surface area of 8.1 x 109 km2.
Is Uranus bigger than Neptune?
Uranus is one of two ice giants in the outer solar system (the other is Neptune). … 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. Uranus gets its blue-green color from methane gas in the atmosphere.
Why is Jupiter the biggest planet?
Jupiter has a dense core of uncertain composition, surrounded by a helium-rich layer of fluid metallic hydrogen that extends out to 80% to 90% of the diameter of the planet. Jupiter’s atmosphere resembles that of the sun, made up mostly of hydrogen and helium.
What’s the biggest planet ever discovered?
TrES-4b is an extrasolar planet, and one of the largest exoplanets ever found, after WASP-12b, WASP-17b, CT Chamaeleontis b (though the latter may be a brown dwarf), GQ Lupi b and HD 100546 b.

What is bigger Jupiter or Saturn?
Q: Which is bigger, Saturn or Jupiter? Even though both Saturn and Jupiter are composed of similar gasses, Jupiter is bigger and denser than Saturn.
How many planets are larger than Saturn?

|(km)||( V )|
|Saturn||58232±6 (136775 for main rings)||764|
Why is Jupiter so much larger than Earth quizlet?
Terms in this set (14) By mass, how much larger than the Earth is Jupiter? … Its extreme mass gives it a very large gravitational pull which warps the paths of comets, asteroids, and other objects which can both cause and prevent collisions with planets.
Why are Jupiter and Saturn the most massive planets in the solar system quizlet?
They are higher in average density than are the terrestrial planets. They are composed mainly of hydrogen, helium, and hydrogen compounds. They are much more massive than any of the terrestrial planets.
Can Saturn fit in Jupiter?
In terms of mass, Earth fits into Jupiter almost 318 times. And just for fun, let’s see how many of all the planets in the Solar System fit into Jupiter: Saturn — 1.73, or 1 whole Saturn.
Can we breathe on Saturn?
First, you can’t stand on Saturn. It’s not a nice, solid, rocky planet like Earth. … Second, like the rest of the planet, the atmosphere on Saturn consists of roughly 75% hydrogen and 25% helium, which means there is little to no oxygen…which means there will be little to no breathing.
