How big is a human compared to the Earth?
The Earth is about 3.5 million times larger than a human.
How big are we compared to the Galaxy?
Answer: Assuming a diameter for the Milky Way galaxy of about 15 kpc, which is about 4.6×10^(17) km, and a diameter for the Earth of about 12756 km, the ratio of the diameter of the Milky Way galaxy to that of the Earth is about 3.6×10^(13).
How many Earths would fit in the Milky Way?
Plugging in our thickness and radius we get about 6.7 X 10^(51) km^3. Dividing the volume of the Milky Way by the volume of the Earth, you get (6.7 X 10^(51))/(10^12) =~ 6.7 X 10^(39) Earths that can fit in the volume of the Milky Way galaxy.
How small is Earth compared to the sun?
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 universe compared to Milky Way?
The observable Universe is 93 billion light-years, yet, our galaxy, the Milky Way, is just 100,000 light-years in diameter.
How many suns fit in Milky Way?
1.5 trillion suns
The Milky Way has a mass of 1.5 trillion suns.
How much bigger is the universe than the Earth?
To a very good approximation, it’s zero. A better approximation – the volume of the earth is about 4/3 pi * (6371 km)^3. The volume of the observable universe (assuming it’s spherical) is 4/3 pi * (46.5 billion light years)^3. So the answer is (6371 km / 46.5 billion light years)^3.
Does the Milky Way have an orbit?
No, the Milky Way is not orbiting anything else, such as the center of the universe, so it has no orbital period. The Milky Way is spinning like a frisbee as it heads out in a straight line from the Big Bang, which happened 14 billion years ago.
How big is the Milky Way galaxy compared to the Earth?
– Tom Answer: Assuming a diameter for the Milky Way galaxy of about 15 kpc, which is about 4.6×10^ (17) km, and a diameter for the Earth of about 12756 km, the ratio of the diameter of the Milky Way galaxy to that of the Earth is about 3.6×10^ (13).
How big is the Milky Way compared to a grain of salt?
Since 5.1 million miles is about 3.2×10^ (11) inches, your ratio of the size of a grain of salt (0.004 inches) to the diameter of the Milky Way is about 8×10^ (13). So, yes, your comparison between a grain of salt and the diameter of the Milky Way is correct.
How big is our home galaxy?
Now we can start to picture how big the galaxy is, and how close we are to other galaxies. With our teeny-tiny, spec of a solar system, our home galaxy would be about 50km (31 miles) in diameter. Our nearest galaxy, Andromeda, would be a mere 1012km (629 miles) away. At this scale the whole observable universe that we can detect is still, well…
What is the ratio of the Milky Way to a peppercorn?
A peppercorn is 0.08 inches in diameter. The Milky Way is 100,000 light years in diameter. The ratio question being asked is Earth (E) is to peppercorn (P) as Milky Way (M) is to unknown (x). This is written as E/P:M/x.
