How big is a grain of sand compared to the Sun?

How big is a grain of sand compared to the Sun?

If the Earth was the size of a grain of sand, the Sun would be about the size of a pool ball (5.5cm or 2.17in).

How many grains of sand can fit in the Earth?

Assuming an average size, calculating how many grains are in a teaspoon, then multiply by all the beaches and deserts in the world, Earth has very roughly 7.5 x 10 to the 18th power grains of sand, or seven quintillion, five hundred quadrillion grains.

How much space does a billion grains of sand take up?

So One Billion grains of Carmel Beach sand is a cube only ~ 1 foot on a side. So if you believe our galaxy has about 50 billion stars that means you only need about 50 cubic feet of Carmel Beach sand (a cube about 3.7 feet on a side) to represent each shining star in our galaxy.

Is it true there are more stars than grains of sand?

Our universe contains at least 70 septillion stars, 7 followed by 23 zeros. Astronomers estimate there exist roughly 10,000 stars for each grain of sand on Earth. That’s a lot of stars.

How many times bigger is the Sun than a grain of sand?

Earth and the moon now fit on the palm of your hand, with the moon going around Earth about once every 28 days. As they’re doing this little waltz in your hand, our two grains of sand are also going around the Sun once a year. On this new scale the Sun is a coconut 109 times bigger than the Earth as a grain of sand.

How many grains of sand are on Earth’s beaches?

If you assume a grain of sand has an average size and you calculate how many grains are in a teaspoon and then multiply by all the beaches and deserts in the world, the Earth has roughly (and we’re speaking very roughly here) 7.5 x 1018 grains of sand, or seven quintillion, five hundred quadrillion grains.

Are there more galaxies in the universe than grains of sand on Earth?

However, it is likely that there are five to ten times most stars than sand on the beaches. In 2016 researchers, observing images from the Hubble Space Telescope stated that there could be more than 2 trillion galaxies in the observable universe, which is ten times more than the highest number expected.

How many grains of sand does it take to fill the Sun?

You can fit about 1 million Earths in the volume of the Sun, so that means we need to add 6 more zeros or orders of magnitude (that is, multiply by 1 million) to calculate the number of grains of sand to fill the Sun:10 39. Let’s now stop thinking about grains of sand, and consider atoms instead!

How many grains of sand are in the Aristarchian Universe?

Archimedes had estimated that the Aristarchian Universe was 10 14 stadiums in diameter, so there would accordingly be (10 14) 3 stadium-spheres in the universe, or 10 42. Multiplying 10 21 by 10 42 yields 10 63, the number of grains of sand in the Aristarchian Universe.

What if our Solar System was a grain of sand?

With our solar system being a grain of sand the observable universe would still be about 37.2 million kilometers in diameter. We Must Go Smaller. If our Milky Way galaxy, which is around 125,000ly across was to be shrunken down to a grain of sand, the observable universe would be roughly 372 meters (1220 feet) wide, not too bad.

How many grains of sand are in a stadium-sphere?

The cube of 10,000 is a trillion (10 12 ); and multiplying a billion (the number of grains of sand in a dactyl-sphere) by a trillion (number of dactyl-spheres in a stadium-sphere) yields 10 21, the number of grains of sand in a stadium-sphere.
