Mercury is almost a perfect sphere - with a diameter of 4879.42 ± 1.0 km
The exact diameter of the geographic north pole (like the south pole) is in theory zero.
The diameter of the moon at the equator is 3476.28 kilometers. Measured from pole to pole, the diameter is 3471.94 kilometers.
Polaris, also known as the north star or pole star.
Pole star WHEN DIRECTION
The brightest star among the other stars in the night sky is called pole star.
North star is the polar star, not the pole star.The North Star is the pole star; it is diredtly above the North pole and is called Polaris. A polar star is a star in close proximity to the polar region such as Sigma Octantis, the Southern star which is close to but not directly over the South pole.
The Pole Star appears to remain stationary because it is directly above the North Pole.
The diameter of the Earth from North pole to South pole is 7,899.83 miles. This is only 25 miles less then the distance around the equator, which is 7,926.41.
Approximately 12,756,320 meters in diameter at the equator. Approximately 12,715,430 meters in diameter from pole to pole.
Yes, the pole star is real and it is also known as Polaris. It is a bright star located almost directly above the North Pole, making it appear stationary as the Earth rotates. The pole star has been used for navigation by many civilizations throughout history.
North StarThe name of the pole star is polaris.Polaris, also called the "North Star".
