Facts about space
The moon doesn't go round us in perfect circles - It gets closer and further away from us at different times of the month. The Tides of the ocean are effected by the moon
Did you know?
The Sun is the star at the center of the Solar System. It is a nearly
perfect sphere of hot plasma, with internal convective motion that
generates a magnetic field via a dynamo process. It is by far the most
important source of energy for life on Earth.
Surface temperature: 5,778 K but the core temperature inside the sun is 15,000,000 Celsius!
Mercury is the closest planet to the sun, and it's also the smallest, only a little bit larger than Earth's moon. Because its so close to the sun (about two-fifths the distance between Earth and the sun), Mercury experiences dramatic changes in its day and night temperatures: Day temperatures can reach a scorching 450 C, which is hot enough to melt lead. Meanwhile on the night side, temperatures drop to minus 180 C.
The second planet from the sun, Venus is Earth's twin in size. Radar
images beneath its atmosphere reveal that its surface has various
mountains and volcanoes. But beyond that, the two planets couldn't be
more different. Because of its thick, toxic atmosphere that's made of
sulfuric acid clouds, Venus is an extreme example of the greenhouse
effect. It's scorching-hot, even hotter than Mercury. The average
temperature on Venus' surface is 465 C. At 92 bar (this is atmosphere), the pressure
at the surface would crush and kill you. And oddly, Venus spins slowly
from east to west, the opposite direction of most of the other planets.
