10) Largest non-spherical solid object: Haumea – 620 km radius.
Largest rocky planet: Kepler 10 c – 2.35 Earth radii (15,000 km).
7) Largest gas giant planet: HD 100546 b – 6 Jupiter radii (419,466 km).
What is the largest rocky planet?
2014. In May 2014, previously discovered Kepler-10c was determined to have the mass comparable to Neptune (17 Earth masses). With the radius of 2.35, it is currently the largest known planet likely to have a predominantly rocky composition.
Which planet has more gas?
Gas Giants: Facts About the Outer Planets. The planets of the solar system as depicted by a NASA computer illustration. Orbits and sizes are not shown to scale. A gas giant is a large planet composed mostly of gases, such as hydrogen and helium, with a relatively small rocky core.
What is the largest thing in existence?
The biggest supercluster known in the universe is the Hercules-Corona Borealis Great Wall. It was first reported in 2013 and has been studied several times. It’s so big that light takes about 10 billion years to move across the structure.
What are the 10 largest objects in the solar system?

Can humans live in higher gravity?
Finding the gravitational limit of the human body is something that’s better done before we land on a massive new planet. Now, in a paper published on the pre-print server arXiv, three physicists, claim that the maximum gravitational field humans could survive long-term is four-and-a-half times the gravity on Earth.
Did Betelgeuse explode?
It’s not only one of Orion’s brightest stars. It’s also a star that astronomers know will one day explode as a supernova. And by one estimate, it’s only 430 light-years away! Follow the links below to learn more about Betelgeuse and its explosive destiny.
What planets are solid gas?
The other planets are not solid. Jupiter, for instance, is made up mostly of trapped helium, hydrogen, and water. In our solar system, the four “gas giants” are Jupiter, Saturn, Neptune, and Uranus. Scientists define planets as dark bodies that orbit around stars.
Is Jupiter only gas?
Composed predominantly of hydrogen and helium, the massive Jupiter is much like a tiny star. But despite the fact that it is the largest planet in the solar system, the gas giant just doesn’t have the mass needed to push it into stellar status.
What’s the smallest gas planet?
The smallest known extrasolar planet that is likely a “gas planet” is Kepler-138d, which has the same mass as Earth but is 60% larger and therefore has a density that indicates a thick gas envelope.
What is the largest black hole?
Astronomers have discovered what may be the most massive black hole ever known in a small galaxy about 250 million light-years from Earth, scientists say. The supermassive black hole has a mass equivalent to 17 billion suns and is located inside the galaxy NGC 1277 in the constellation Perseus.
What’s the heaviest thing in the world?
The heaviest object ever directly weighed was the Revolving Service Structure (RSS) of launch pad 39B at NASA’s Kennedy Space Center, Florida, USA. The structure was lifted up on 21 jacking points which, between them, measured the mass of the RSS as 2,423 tonnes (5,342,000 lbs).
What is the oldest thing in the universe?
With a redshift of z = 8.2, at the time of observation, the burst was the most distant known object of any kind with a spectroscopic redshift. GRB 090423 was also the oldest known object in the Universe, as the light from the burst took approximately 13 billion years to reach Earth.
What is the largest known non Planet object in the solar system?
1.) Ganymede: Jupiter’s largest moon is the largest non-planet in the Solar System. With a diameter of 5,268 km (3,271 miles), it’s 8% bigger than the planet Mercury, although it has less than half the mass of our Solar System’s innermost planet, being made of mostly ices and silicate minerals.
Are any moons bigger than Earth?
However, not all of the moons are smaller than all of the planets. There are seven moons in our Solar System, including our own Moon, that are larger than Pluto. Jupiter’s moon Ganymede is the largest moon in the Solar System, and Ganymede as well as Saturn’s moon Titan are both larger than Mercury and Pluto.
Is Jupiter the largest object in the solar system?
Largest Planet: Jupiter. The largest planet in our solar system by far is Jupiter, which beats out all the other planets in both mass and volume. Jupiter’s mass is more than 300 times that of Earth, and its diameter, at 140,000 km, is about 11 times Earth’s diameter.
How many G’s can kill you?
While John Stapp showed that people can withstand much higher G forces than had long been thought, there is a limit to what anyone can take. Princess Diana tragically proved that. Experts estimate that, in the car accident that killed her, the G forces on her chest were about 70 G’s (and 100 G’s on her head).
At what distance from the Earth is gravity zero?
In fact, at an altitude of 400 kilometres (250 mi), equivalent to a typical orbit of the ISS, gravity is still nearly 90% as strong as at the Earth’s surface. Weightlessness actually occurs because orbiting objects are in free-fall.
How does zero gravity affect the human body?
For one thing, it tells muscles and bones how strong they must be. In zero-G, muscles atrophy quickly, because the body perceives it does not need them. The muscles used to fight gravity –like those in the calves and spine, which maintain posture– can lose around 20 per cent of their mass if you don’t use them.
Will Betelgeuse turn into a black hole?
By contrast, the Sun will not become a red giant until its age reaches 10 billion years, another 5 billion years from now. Red giants that are at least twice as heavy as Betelgeuse later become black holes after a supernova explosion. Betelgeuse is too faint in X-rays to be detected.
How did Betelgeuse die?
Dying Star Betelgeuse Keeps Its Cool and Astronomers Are Puzzled. A direct-sky image of Betelgeuse, a star that is shedding its mass as it nears the end of its life. This phase of star death is extremely common in the universe — in about 5 billion years, when the sun starts to die, it too will become a “red giant.”
What if Betelgeuse exploded?
At only 600-or-so light years distant, Betelgeuse will be far closer than any supernova ever recorded by humanity. It’s fortunately still far away enough that it poses no danger to us. Not only will Betelgeuse be visible during the day, but it will rival the Moon for the second-brightest object in the sky.
Can you stand on Pluto?
Pluto is only about two-thirds as wide as Earth’s moon and has about the same surface area as Russia. As a comparison, on Earth, you could blot out the full moon with your thumb if you held out your arm, but it would take almost your entire fist to block Charon while standing on Pluto, Stern said.
Is Mars a gas planet?
When the solar system settled into its current layout about 4.5 billion years ago, Mars formed when gravity pulled swirling gas and dust in to become the fourth planet from the Sun. Mars is about half the size of Earth, and like its fellow terrestrial planets, it has a central core, a rocky mantle and a solid crust.
What lives on Jupiter?
Since Jupiter has no solid surface, Jovian aliens would have to float or fly, surviving in extreme conditions too harsh for any Earthling. Still, at certain altitudes in Jupiter’s atmosphere, there do exist chemicals that are necessary for some sort of exotic life form.
Which planet has the most beautiful rings?
What planets have ice?
An ice giant is a giant planet composed mainly of elements heavier than hydrogen and helium, such as oxygen, carbon, nitrogen, and sulfur. There are two ice giants in the Solar System: Uranus and Neptune.
Is Pluto a gas planet?
Lying 30 to 50 times as far from the sun as Earth, Pluto’s composition bears a greater resemblance to the rocky terrestrial planets than the gas giants that are its neighbors. New Horizons revealed that the surface of the dwarf planet appears to be dominated by nitrogen ice, with methane and carbon mixed in.
