Because of the discrepancy between Earth’s polar and equatorial diameter, astronomers and scientists often employ averages. This is what is known as its “mean diameter”, which in Earth’s case is the sum of its polar and equatorial diameters, which is then divided in half. From this, we...
When the moon moves completely into the Earth's dark shadow cone (called the "umbra") we call that a total lunar eclipse. At the moon's average distance from Earth of 239,000 miles [383,000 km], the umbra measures roughly 5,800 miles [9,334 km] in diameter. The moon is about 2...

Atotal solar eclipseoccurs when the moon passes between the sun and Earth, completely obscuring the face of the sun. These solar eclipses are possible because the diameter of the sun is about 400 times that of the moon, but also approximately 400 times farther away, says theNatural History ...
Elon Musk has made a lot of predictions about Mars, including that we could have thebeginnings of a human colony this decade. Musk envisions a fleet of more than 100 Starships, gathering in orbit of Earth to depart en masse for Mars every 26 months when the planet is closest. Each of ...
The length of a line drawn straight through the center of a circle and extending out to its edges is called the diameter. Dividing the circumference by the diameter of any and all circles will yield the same result: pi — and that's true for all circles, regardless of size....
(but not hit) Earth on April 13, 2029. NASA’s OSIRIS-REx spacecraft, the one that dropped off samples of the asteroid Bennu last year, is still in space and will rendezvous with Apophis after it passes Earth, but scientists also want to collect data before it gets here. That way ...
According to Christian legend, the first pink carnation on Earth grew from Mary’s tears when she wept for Jesus as he carried his cross. Therefore, a pink carnation often symbolizes a mother’s unyielding love. Carnations in the Garden There are two main groups of carnations: border or ga...
making them incredibly dense. This means that their gravitational pull is immense, for example, on the surface of a neutron star gravity is around 1 billion times stronger than its pull on Earth. This makes neutron stars a great test subject to challenge predictions in Einstein's theories, suc...
