# if the earth was the size of a marble how big would the sun be

## If The Earth Was The Size Of A Marble How Big Would The Sun Be?

If Earth was 1cm diameter (marble size) the sun would have a diameter of 110cm & be 117 meters away. It’s an interesting exercise to reduce the size of our Solar System, to a size we can recognise but keep it in scale.

## What if Earth was the size of the Sun?

If our world was as big as the Sun, then, like the water, our soil would have to be spread out to cover a much larger space. Less soil would mean less food, while the demand for food would stay the same.

## How big would the Sun be if the Earth was the size of a pea?

If you mean everything is scaled down by the same factor, then as the Earth (with a diameter of 12000km) has been scaled down to the size of a pea (with diameter 6mm) then the Sun (diameter 1.4 million km) now has a diameter 700mm, or 70cm. This could be roughly the size of a medium sized exercise ball.

## How big would the Earth be if the Sun was a grapefruit?

If the sun were a large grapefruit (r~ 7 cm), the Earth would be a pinhead 15 meters away. The Solar System; Sizes are to scale, but distances are not.

## Is Earth the size of a marble?

In their fantastic model, the Earth is only the size of a small marble. Even then, seven miles of open space was needed to show the entire solar system from the Sun to Neptune (sorry, Pluto).

## What if the Earth was 10 times bigger?

If the hypothetical super-Earth were even bigger, say, 10 times its current mass, dramatic changes could start happening in Earth’s interior. The iron core and liquid mantle would also be 10 times larger, and with more gravity acting on a larger mass, the pressure beneath Earth’s surface would increase.

## What if the sun exploded?

The good news is that if the Sun were to explode – and it will eventually happen – it wouldn’t happen overnight. … During this process, it will lose its outer layers to the cosmos, leading to the creation of other stars and planets in the same way that the violent burst of the Big Bang created Earth.

## Is about 93 million miles away from Earth?

Answer 4: The Sun is about 150 billion meters (or 93 million miles) away from the earth. It will take a bit more than eight minutes for the light to travel from the sun to the earth.

## What is the planet size compared to Earth?

Earth is nearly 13,000 kilometers across. The smallest terrestrial planet, Mercury, has a diameter about 40 percent of that size. Jupiter, the biggest planet, is more than ten times larger than Earth. The maximum possible size for a planet is a few times larger than Jupiter – about the same size as the smallest stars.

## What is the size relative to Earth?

The inner solar system
Object Eq. Diameter (km) Size Relative to Earth
Venus 12,104 0.95x
Earth 12,756 1.00x
Mars 6,792 0.53x
Ceres 950 0.07x

## How small Earth is in the universe?

Meaning that Earth makes up about 0.0003% of the total mass of our solar system. For comparison, Earth makes up about 0.2% of the total mass of the planets. We orbit the sun at an average distance of 93 million miles, which is equal to 1 Astronomical Unit.

## Is the Earth 1/4 diameter of the sun?

The diameter of the Sun is 1. 4×109 m and the diameter of the Earth is 1.

## What is the grapefruit scale?

On this initial scale, the Earth is the size of the globe. The Moon is about the size of the grapefruit. The distance between the two is 12 meters.

Scale 1: 1 / 31.9 million (1 cm = 319 km)
Object Moon 3,476 km 0.01 second 11 cm grapefruit

## Why does Earth look like a marble?

The Earth goes around the sun. The path it takes is called its orbit. … When you look at Earth from space, it looks like a big, blue marble. The Earth looks blue because of water.

## Can humans live on a Super Earth?

To live on a Super Earth would require super strength. If Earth were 10 times larger, gravity would be 10 times stronger. This is based on the formula of Surface Area = Mass/Radius squared. … Technically, our skeletons can withstand a force more than 90 times that of the Earth’s gravity, but only when standing still.

## Can the Earth lose gravity?

Over the next few billion years, Earth’s gravity will change by tiny amounts because of several events. As the sun expands, the oceans will boil off into space, reducing the planet’s mass and therefore cutting the force of its gravity. But Earth’s core will also cool, so the planet will experience thermal contraction.

## Can the Earth get too heavy?

But, considering the planet as a whole, does that get heavier over time? The answer is yes, it can. … Debris, dust and other stuff raining in from space contributes a huge amount of weight to the Earth every single year.

## Can we live without the Sun?

Without the Sun’s rays, all photosynthesis on Earth would stop. … While some inventive humans might be able to survive on a Sun-less Earth for several days, months, or even years, life without the Sun would eventually prove to be impossible to maintain on Earth.

## Will the Sun become a black hole?

Will the Sun become a black hole? No, it’s too small for that! The Sun would need to be about 20 times more massive to end its life as a black hole. … In some 6 billion years it will end up as a white dwarf — a small, dense remnant of a star that glows from leftover heat.

## What would happen if there was no moon?

The moon influences life as we know it on Earth. It influences our oceans, weather, and the hours in our days. Without the moon, tides would fall, nights would be darker, seasons would change, and the length of our days would alter.

## How long would it take to get to the Sun?

It would be faster to fly to the sun: It would take 169,090 hours to fly there at 550 miles per hour. It would take 7,045 days to fly there at 550 miles per hour. It would take 19.3 years to fly there.

## What does it mean for the earth to rotate?

Earth’s Rotation

Earth spins around its axis, just as a top spins around its spindle. This spinning movement is called Earth’s rotation. At the same time that the Earth spins on its axis, it also orbits, or revolves around the Sun. This movement is called revolution.

## Is any planet bigger than the sun?

Explanation: To begin with planets, as that is the easiest question to answer, there are no planets bigger than the Sun or even close to the size of the Sun. At about 13 times the mass of Jupiter a planet becomes what is referred to as a “brown dwarf”.

## Is there gravity on every planet?

Yes! Anything that has mass has gravity. The more mass something has (the bigger it is), then the more gravity it will have. So everything around us (including all the planets) have gravity!

## Which planet is almost big as Earth?

Jupiter
The largest planet in the solar system, the gas giant Jupiter is approximately 318 times as massive as Earth. If the mass of all of the other planets in the solar system were combined into one “super planet,” Jupiter would still be two and a half times as large.Jul 20, 2018

## What is the size of the sun and planets?

The Sun has a radius of 696.340 km / 432.685 mi and a diameter of 1.39 million km / 864.000 mi. Earth, for comparison, has a radius of only 2.439 km / 1.516 mi, and a diameter of just 12.742 km / 7.917 mi. All the planets in our Solar System combined account for just 0.2% of the Sun’s mass.

## 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.”

## Does black hole have gravity?

Black holes are points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can escape the powerful tug of a black hole’s gravity.

## What is bigger than a Universe?

No, the universe contains all solar systems, and galaxies. Our Sun is just one star among the hundreds of billions of stars in our Milky Way Galaxy, and the universe is made up of all the galaxies – billions of them.

## What is the biggest thing in the universe?

Hercules-Corona Borealis Great Wall
The largest known structure in the Universe is called the ‘Hercules-Corona Borealis Great Wall’, discovered in November 2013. This object is a galactic filament, a vast group of galaxies bound together by gravity, about 10 billion light-years away.

## How old is the earth?

4.543 billion years

## Is the Sun 108 times Earth?

The distance of Earth from the Sun is about 108 times the diameter of the Sun (actually closer to 107.51, as per definition of the AU). Actual ratio varies between 105.7 (Perihelion) and 109.3 (Aphelion). The distance between the Earth and the Moon is also about 108 times the diameter of the Moon.
