how many miles is the world

Earth’s circumference (the distance all the way around the equator) is 24,901 miles (40,075 kilometers). Its diameter (the distance from one side to the other through Earth’s center) is 7,926 miles (about 12,756 kilometers).

How many times around the earth is 1 million miles?

Maine Man’s Car Logs One Million Miles, Equivalent to Driving Around Earth 40 Times.

Is the Earth 8000 miles?

The diameter of Earth, about 8,000 miles, is about 4 times the diameter of the moon.

How big is the world?

6,371 km

How fast is the Earth spinning?

roughly 1,000 miles per hour
The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40,075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second–or roughly 1,000 miles per hour.

Can you drill through Earth?

First, let us state the obvious: You can’t drill a hole through the center of the Earth. … To date, the deepest hole is the Kola Superdeep Borehole. Drilling started in the 1970s and finished some 20 years later when the team reached 40,230 feet (12,262 meters). That is about 7.5 miles, or just over 12 km.

How old is the Earth?

4.543 billion years

How many Earths can fit in the sun?

1.3 million Earths
If you divide the volume of the sun by the volume of the Earth, you get that roughly 1.3 million Earths can fit inside the sun.

Where does the Earth start and end?

Earth ends and outer space starts at the Kármán line, some 62 miles (100 kilometers) above the planet’s surface.

How big is the moon?

1,737.4 km

How much weight is the Earth?

5.972 × 10^24 kg

How thick is the Earth in miles?

At close to 3,000 kilometers (1,865 miles) thick, this is Earth’s thickest layer. It starts a mere 30 kilometers (18.6 miles) beneath the surface.

How big is the Earth compared to a human?

The Earth is about 3.5 million times larger than a human.

How big is the earth compared to the sun?

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.

Is Earth bigger than Mars?

With a radius of 2,106 miles, Mars is the seventh largest planet in our solar system and about half the diameter of Earth. Its surface gravity is 37.5 percent of Earth’s. … For one, Mars is on average about 50 percent farther from the sun than Earth is, with an average orbital distance of 142 million miles.

Why don’t we feel the earth moving?

Bottom line: We don’t feel Earth rotating on its axis because Earth spins steadily – and moves at a constant rate in orbit around the sun – carrying you as a passenger right along with it.

What if Earth stopped spinning?

At the Equator, the earth’s rotational motion is at its fastest, about a thousand miles an hour. If that motion suddenly stopped, the momentum would send things flying eastward. Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes.

How fast does the sun move?

200 kilometers per second
The sun and the solar system appear to be moving at 200 kilometers per second, or at an average speed of 448,000 mph (720,000 km/h). Even at this rapid speed, the solar system would take about 230 million years to travel all the way around the Milky Way. The Milky Way, too, moves in space relative to other galaxies.Sep 1, 2021

Can the Earth fall?

Thanks to gravity, the earth does fall. It is actually in a constant state of falling since it is in orbit around the sun. This gravitational pull that the sun has on the earth is useful since it stops earth from catapulting into space.

Is it possible to dig to China?

To dig to China, you’d need to start your journey from Chile or Argentina — the location of China’s antipode (or opposite point on Earth). You would need a super-powered drill to get through rock and metal within Earth’s three layers.

What would happen if you jumped into a hole through the Earth’s center?

If you jumped into the tunnel, you’d fall down towards the center of the Earth, accelerating constantly, thanks to gravity. By the time you reached the halfway point, after falling for 21 minutes, you’d be traveling at 28,000 kilometers per hour.

When did life appear on Earth?

3.7 billion years
The earliest life forms we know of were microscopic organisms (microbes) that left signals of their presence in rocks about 3.7 billion years old.

Who discovered Earth?

By around 500 B.C., most ancient Greeks believed that Earth was round, not flat. But they had no idea how big the planet is until about 240 B.C., when Eratosthenes devised a clever method of estimating its circumference.

When did life first evolve?

3.77 billion years ago
The earliest time that life forms first appeared on Earth is at least 3.77 billion years ago, possibly as early as 4.28 billion years, or even 4.41 billion years—not long after the oceans formed 4.5 billion years ago, and after the formation of the Earth 4.54 billion years ago.

How many galaxies are there?

The Hubble Deep Field, an extremely long exposure of a relatively empty part of the sky, provided evidence that there are about 125 billion (1.25×1011) galaxies in the observable universe.

How many galaxies are in the universe?

Added to existing Hubble observations, their results suggested such galaxies make up 90 percent of the total, leading to a new estimate—that there may be up to two trillion galaxies in the universe.

What is largest known star?

The largest known star in the universe is UY Scuti, a hypergiant with a radius around 1,700 times larger than the sun. And it’s not alone in dwarfing Earth’s dominant star.

How long is 1 hour in space?

Answer: That number times 1 hour is 0.0026 seconds. So a person at that deep space location would have a clock that would run for one hour, while that person calculated that our clock ran for 59 minutes, 59.9974 seconds.

How is space cold?

In space, there is no air or water, so the only way to lose heat is by radiation, where your warm and wiggly atoms release energy directly into space.

Where does space end?

Interplanetary space extends to the heliopause, whereupon the solar wind gives way to the winds of the interstellar medium. Interstellar space then continues to the edges of the galaxy, where it fades into the intergalactic void.

How cold is the Moon?

The average temperature on the Moon (at the equator and mid latitudes) varies from -298 degrees Fahrenheit (-183 degrees Celsius), at night, to 224 degrees Fahrenheit (106 degrees Celsius) during the day.
