We cover everything from solar power cell technology to climate change to cancer research. 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 Mercury has a very thin atmosphere of oxygen, sodium, hydrogen, helium and potassium and can't break-up incoming meteors, so its surface is pockmarked with craters, just like the moon. One day on Mars is almost equal to one day on Earth, while Mars has a solar year of about 2 Earth years (687 days). it is believed that Jupiter’s core consists of an exotic form of liquid metallic hydrogen surrounding a solid core of unknown composition. Uranus had been identified before by ancient societies but was misclassified as a star. The 4 most well-known are Io, Europa, Ganymede, and Callisto, first discovered by Galileo.The sixth planet from the sun, Saturn is the second gas giant in the system and the second largest planet.

Mars has two sister moons, known as Phobos and DeimosJupiter is the largest planet in the solar system and contains the majority of the mass of the planets.

In addition to the 8 planets and their respective moons, there is a handful of dwarf planets, comets and asteroids occupying our solar neighborhood.Our solar system is over 4 billion years old and was formed from the compressed remains of a giant interstellar molecular cloud. With pictures of each planet, this poster will add a bit of fun and colour to your classroom or home. That tilt causes extreme seasons that last 20-plus years, and the sun beats down on one pole or the other for 84 Earth-years at a time. Much like Jupiter, numerous pictures have been taken of the planet by a combination of ground-based telescopes, space telescopes and orbital spacecraft.
