For comparison, if Earth were the size of a grain of sand, the Sun would be around the size of a billiard ball (5.5cm or 2.17in).

What if the Earth was as big as the Sun?
If our globe were as vast as the Sun, then our soil would have to be stretched out to cover a much bigger area, similar to how water is spread out to cover a much larger area. This is because the Sun’s mass is so vast that its gravitational attraction pulls other planets into the Sun’s orbit, which is the reason why our Solar System moves the way it does currently.
How many grains of sand would fill the universe?
Using modern notation, Archimedes estimated that it would take one billion and sixty-three billion grains of sand to completely fill the known cosmos at the time of his discovery.
Are there more universes than grains of sand?
There may be more Earth-like planets in the universe than there are grains of sand on all of our beaches combined. According to new study, the Milky Way alone has billions of potentially livable planets — and that’s just a fragment of the universe’s total population.
What if Earth was 10x bigger?
If the hypothetical super-Earth were much larger, say ten times the current mass of the planet, major changes in the planet’s interior may begin to take place. As a result, the iron core and liquid mantle would be ten times bigger, and since greater gravity would be acting on a larger mass, the pressure under the Earth’s surface would grow.
Can the Earth lose gravity?
Several events will cause the Earth’s gravitational field to shift by very small amounts during the next few billion years. As the sun expands, the seas will boil away into space, lowering the mass of the planet and, as a result, diminishing the power of its gravitational pull. However, because the Earth’s core will cool as well, the globe will undergo thermal contraction.
How many grains of sand are in galaxies?
The total number of sand grains computed was seven quintillion five quadrillion (that’s 7.5 followed by seventeen zeros, or 7.5 billion billion)!
Are there more atoms in a grain of sand than sand on Earth?
So, let’s start with the simple part (for chemists): how many atoms are there in a grain of sand, exactly? Due to the fact that every molecule contains three atoms, we increase this result by three. The answer is 3.0121022, which is 3.0121022. (Spoiler alert: pay close attention to this part.) This means that one grain of sand has 43 quintillion atoms.
How much sand is left in the world?
The Earth contains about (and this is a very rough estimate) 7.5 times 10 to power of 18 grains of sand when all of the sand from all of the beaches and deserts on the planet is combined; in other words, seven quintillion, five hundred quadrillion grains of sand are added together.
What would happen if a grain of sand hit Earth at light speed?
Because the likelihood that a particle of sand traveling at or near the speed of light would really make it to the surface of the planet is so small, it is best to reject the possibility altogether. A grain of sand traveling at such speed and colliding with the atmosphere would be completely annihilated before it ever reached the surface of the Earth.
How fast would a grain of sand have to travel to destroy the earth?
If nothing happens to them, they will retain their current velocity until something causes them to change direction. However, in order to escape the gravity of a world, they must reach escape velocity (for the earth, this is 11.2 km/s). At such speed, they are almost certainly capable of causing significant damage, but it is difficult to predict how much.
How many stars are in a grain of sand?
According to astronomers, there are around 10,000 stars for every grain of sand on the planet. That is a significant number of stars. The origin of sand grains has just been found by astronomers.
What is sand made of?
Sand is typically composed of varying amounts of material weathered from inland rocks (or seacliff material) and transported to the beach by the wind or rivers, as well as shells and other hard parts precipitated out of the ocean water by marine organisms. Sand is also composed of varying amounts of material weathered from inland rocks (or seacliff material) and transported to the beach by the wind or rivers. As a result, sand records processes that occur across a wide range of periods.
How many galaxies are there in the universe?
Overall, Hubble has revealed an estimated 100 billion galaxies in the cosmos, but this figure is expected to rise to about 200 billion as space telescope technology improves, according to Livio, who spoke to Space.com about the findings.
