One Earth Day is 24 hours, a lunar day is 28 days, 12 hours, 44 minutes longer than this.
On average, a lunar day is 29 days, 12 hours, 44 minutes long, which is the time taken for the moon to go through all of the phases. It orbits the earth once every 27 days and 8 hours, but takes a little longer to complete lunar day due to the earths precession around the sun in that time.
1,321 Earths can fit in Jupiter.
Jupiter's year is longer than Earth's year because it is further away from the sun and takes more time to complete one orbit. Jupiter's distance from the sun means it has a larger orbit to travel around, which results in a longer year.
The Earth's core will continue to have heat for billions of years. It is estimated that the core will remain hot for another 1 to 1.5 billion years before it cools down significantly.
Water 75%
When a lunar eclipse is in progress, it's visible from any point on earth where the moon is in the sky, i.e. nominally 1/2 of the earth.
It's because of the relative sizes of the Sun, moon and Earth. the moon - being the smallest of the three - casts a small shadow - and thus a solar eclipse rarely lasts more than a few minutes. The shadow cast by the Earth in a lunar eclipse is much larger - and thus the lunar eclipse lasts much longer.
70% or 80% of water covers the earths surface
1,321 Earths can fit in Jupiter.
In terms of volume, 1320 Earths.
The core is 33% of the Earths mass
1G
about 30%
it is 10N/Kg
Much longer
Fossils, although technically they are not preserved in the earths crust; the minerals in the bones and pore spaces have been replaced by other harder minerals which take much longer to weather.There are a number of different fossilization processes. See this link :How are Fossils Formed?
If there is much water on the Moon, it will be much easier for lunar colonists to survive there.
During a lunar eclipse, the three bodies are lined up on the same straight line. The Earth is the one in the 'middle', but much much much closer to the moon than it is to the sun.
