what is the size of earth??

About 25,000 miles in circumference at the equator, eight thousand from pole to pole.

The Earth's circumference at the equator is 24,901.55 miles. Since the Earth rotates, it bulges outward at the equator, resulting in a measurement that is larger than if Earth did not rotate. Also, since it bulges at the equator, it contracts at the poles, resulting in a much smaller measurement than the equator: 24,859.82 miles.

No, the circumference is nearer 24,900 miles at the equator, if by planet you mean Mother Earth.

The sun is by far the largest object in our solar system. It contains 98% of the solar system's total mass.\n\nIt would take 109 earths to stretch across the sun, and it would take over one million earths to "fill up" the sun if it were hollow.\n\nIf you think of the sun as being the size of a basketball, then the earth would be about the size of the head of a pin.\n\nThe diameter of the Sun is 865,400 mi \nEarth equatorial diameter=7926 mi (12760 km)\nEarth polar diameter=7900 mi (12720 km)\n\nSun's surface area is approximately 12,000 times that of Earth.\n\nMore info:

The length of Earth's equator is about 40,075.0 km, or 24,901.5 miles.

The circumference of the earth at the equator is 24,901.55 miles (40,075.16 kilometers).\nBut, if you measure the earth through the poles the circumference is a bit shorter - 24,859.82 miles (40,008 km). This the earth is a tad wider than it is tall, giving it a slight bulge at the equator. This shape is known as an ellipsoid or more properly, geoid (earth-like).

not sure about the mass and size, i always thought mars is bigger than earth? just are you sure your questions are sensible coz as far as i remember, we on earth are still trying to figure out how to get there.

This is a simple ratio problem. The equation would be Dgalaxy/Dearth=Dearth/x so x=(Dearth)^2/Dgalaxy. Asssuming a parsec is 3.6 light years, and a light year is 5.87 trillion miles and the diameter of the Earth is 8,000 miles, then the Earth would be 0.001 millimeter or one micron in size, which is the size of an average bacterium, maybe? Very cool. Oops! I re-did my calculation and I see that I made a factor of ten error. The correct answer is about 0.1 microns, or the size of some viruses. But tell me how you would make such a model of the Earth?

mass of Earth = 5.9742 × 1024 kilograms

the circumference of the earth at the equator is exactally 24,902 mi (40,076 km)

The circumference of the earth from pole to pole is roughly 24,860 miles. Since the distance of the north pole to the equator is 1/4 of the circumference then I calculate it to be approximately 6215 miles.\n\n:)

Earth is roughly 8,000 miles in diameter, and 25,000 miles in circumference.

At the equator, the earth is approx 24,000 in circumference.  So, how fast can you walk? That's how long it will take.  HINT:  Go to the North or South pole and walk around in a little circle, then you've gone "around" all the longitudes of the whole world in a few steps.

The smallest anything can be is called Plank length and it is approximately 1.6 × 10 (to the -35th power) meters.  \nAssuming "we" is the earth, we are very small compared to the size of the universe.  The "volume" of the observable universe is about  1.9 × 10 (to the 33rd power) light years, and the earth has a volume of approximately 8.2 x 10 (to the 12th power) miles, or 4 x 10 (to the -26 power) of a light year.  The universe, then, is about 4.7 x 10 (to the 58th power) times bigger than the earth.

Mars is much smaller than Earth.  About 1/2 the diameter (0.53), and 1/10 of the mass (0.107) of the Earth.\n\nHere's a great set of illustrations showing the relative sizes of all the planets, and the sun.\n\nhttp://www.comagz.com/webmagazine/story/proportions_how_small_we_are

It would take about 57000 Earths to span the classical diameter of an electron.\n\nThe universe has been in existence for 1.37E+10 years.  It would therefore be somewhere around that many lightyears in radius.  That's 1.296E+23 kilometers.\n\n(In fact, the universe is probably larger than this because of the inflationary expansion during which space appeared as a consequence of the relaxation of the primordial energy that created the universe to begin with.)\n\nEarth's radius is 6378 kilometers, which means that it would take 2.032E+19 Earths to span across the universe.\n\nOn a scale at which the universe is one meter wide, Earth's radius would be 4.921E-20 m.  The classical radius of an electron is 2.82E-15, so the electron (in the real world) would be (classically speaking) 57000 times wider than Earth (in the model).\n\nHowever, the Planck length is 1.616E-35 meters, and so even the scaled down Earth is still 3.045E+15 Planck lengths in radius.  If the Planck length were scaled UP by the same amount, it would still be only about 21 Angstroms long: about the wavelength of x-rays.

The earth is not a perfect sphere. It's slightly 'wider' than it is tall, so you could measure the circumference at the equator (24,901.55 miles or 40,075.16 kilometers). If you go through the south and north poles (24,859.82 miles or 40,008 km)
