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.
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.
Is the Moon the size of a golf ball?
The size of the golf ball Moon is about ¼ the width of our “Earth” heads, but the distance of an arm’s length is much too short.
Is the sun 3 times the size of Earth?
The Sun is 864,400 miles (1,391,000 kilometers) across. This is about 109 times the diameter of Earth. The Sun weighs about 333,000 times as much as Earth.
How big is the size of a pea?
Tumor sizes are often measured in millimeters (mm) or centimeters. Common items that can be used to show tumor size in mm include: a sharp pencil point (1 mm), a new crayon point (2 mm), a pencil-top eraser (5 mm), a pea (10 mm), a peanut (20 mm), and a lime (50 mm).
How big is Earth compared to the universe?
How large is the universe compared to Earth? The Diameter of the earth is 12,742 km. One parsec is about 30 Trillion km -thats 30,000,000,000,000 km. The observable universe is about 28 Billion parsecs across.
What would happen 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 would happen if the Sun was bigger than it is now?
What would happen if the sun was bigger or smaller? If for any reason the Sun shrank smaller than the Earth, this shrunken Sun wouldn’t have the mass to create fusion and would burn out completely. Our solar system would lose its only star. … Earth’s mass would be at least 333,000 times bigger than it is now.
Can you throw a rock from the moon to Earth?
You could, but it wouldn’t be super easy. First of all, you have to get off of the Moon. The escape velocity of the Moon is around 2.38 km/s, which is a good estimate of what you would need to leave the Moon’s sphere of influence. About 700 m/s of that is the orbital velocity.
Why are there 3 golf balls on the moon?
Alan Shepard, part of the Apollo 14 mission, stands as the only person to hit golf balls on the moon. During the mission, Shepard took a few swings and ended up leaving two golf balls to live on the moon forever. Apparently, he fitted an 6 iron head to the handle of a lunar sample collection device.
How long would it take to fall from the moon to Earth?
4.83 days, if you stopped its sideways motion instantly and let it fall.
Can you fit 1 million Earths in the Sun?
The sun lies at the heart of the solar system, where it is by far the largest object. It holds 99.8% of the solar system’s mass and is roughly 109 times the diameter of the Earth — about one million Earths could fit inside the sun.
How many times is the Sun bigger than the Earth?
The Short Answer:
Our Sun is a bright, hot ball of hydrogen and helium at the center of our solar system. It is 864,000 miles (1,392,000 km) in diameter, which makes it 109 times wider than Earth.
How many suns fit in the biggest star?
The largest known star in the universe, UY Scuti is a variable hypergiant with a radius around 1,700 times larger than the radius of the sun. To put that in perspective, the volume of almost 5 billion suns could fit inside a sphere the size of UY Scuti.
