All meridians of longitude join the Earth's north and south pole, so the length of every meridian is 1/2 of the Earth's polar circumference.
Earth is wider around the equator than around the prime meridian. This is due to the fact that the Earth is not a perfect sphere but an oblate spheroid, meaning it is slightly flattened at the poles and bulging at the equator.
The meridian exactly halfway around the world from the prime meridian is called the 180th meridian or the antimeridian. This line represents the opposite side of the Earth from the prime meridian and is where the International Date Line is located.
The International Date Line combined with the Prime Meridian makes a complete circle around the Earth. The Prime Meridian is at 0 degrees longitude, and the International Date Line is opposite it at 180 degrees longitude.
-- The longitude of the Prime Meridian is zero. -- Every point on the Prime Meridian has a different latitude. -- For every possible latitude, there is a point on the Prime Meridian.
The prime meridian encircles the entire earth, which means it is the same length as the earth's circumference, which is 24,901.55 miles.
The prime meridian encircles the entire earth, which means it is the same length as the earth's circumference, which is 24,901.55 miles.
The Prime Meridian only extends from the North Pole to the South Pole along the 0° longitude line,which is only half of the Earth's circumference.The circumference of the Earth that includes the Prime Meridian is a polar circumference measuring approximately 40,008 km (about 24,860 miles), which is shorter than the equatorial circumference by about 67 km (42 miles), not including elevation above or below MSL.

The International Date Line combined with the Prime Meridian makes a complete circle around the Earth. The Prime Meridian is at 0 degrees longitude, and the International Date Line is opposite it at 180 degrees longitude.
The Prime Meridian and the meridian of 180° longitude combine to form a great circle on the Earth. Each of them alone is a semi-circle.
-- The longitude of the Prime Meridian is zero. -- Every point on the Prime Meridian has a different latitude. -- For every possible latitude, there is a point on the Prime Meridian.
The line name at 0 degrees longitude is commonly referred to as the Prime Meridian. This line passes through Greenwich, London, United Kingdom and can also be referred to as the International Meridian or Greenwich Meridian.
The prime meridian divides the Earth into the Eastern Hemisphere and the Western Hemisphere.
No. The equator is a full circle all the way around the Earth ... about 24,900 miles (40,074 kilometers). The Prime Meridian is a semi-circle between the north and south poles ... about 12,409 miles (19,970 kilometers).
