The Solar System The following presentation will share interesting information about our solar system.

The Sun The sun is the largest object in the Solar System The Sun is, at present, about 70% hydrogen and 28% helium The temperature is 15.6 million Kelvin and the pressure is 250 billion atmospheres. The diameter is 1,390,000 km. The mass is 1.989e30 kg The temperature is 5800 K (surface) 15,600,000 K (core) Right now our sun is about 4.5 billion years old and Since its birth it has used up about half of the hydrogen in its core.

Mercury Mercury is the closest planet to the sun Temperature on Mercury are the most extreme in the solar system ranging from 90 K to 700 K. The temperature on Venus is slightly hotter but very stable Mercury is the second most major body in the Solar System, after Earth. Earth's density is due in part to gravity; if not for this, Mercury would be denser than Earth Mercury's orbit is highly eccentric it is only 46 million km from the Sun.

Venus Venus is a dim world of intense heat and volcanic activity. Similar in structure and size to Earth, Venus' thick, toxic atmosphere traps heat in a runaway greenhouse effect. The scorched world has temperatures hot enough to melt lead. Glimpses below the clouds reveal volcanoes and deformed mountains. Venus spins slowly in the opposite direction of most planets.  When using special satellite technology to penetrate the clouds. When looking through a normal telescope 

Earth Everyone knows that NASA studies space; fewer people know that NASA also studies Earth. Since the agency’s creation almost 50 years ago, NASA has been a world leader in space-based studies of our home planet. Our mission has always been to explore, to discover, and to understand the world in which we live from the unique vantage point of space, and to share our newly gained perspectives with the public. Those who intend to use the Blue Marble: Next Generation in their own publications or projects should be aware of areas that still require improvement. Areas of open water still show some “noise.” In tropical lowlands, cloud cover during the rainy season can be so extensive that obtaining a cloud-free view of every pixel of the area for a given month may not be possible. Deep oceans are not included in the source data; the creator of the Blue Marble uses a uniform blue color for deep ocean regions, and this value has not been completely blended with observations of shallow water in coastal areas.

Mars Mars is a cold desert world. It is half the diameter of Earth and has the same amount of dry land. Like Earth, Mars has seasons, polar ice caps, volcanoes, canyons and weather, but its atmosphere is too thin for liquid water to exist for long on the surface. There are signs of ancient floods on Mars, but evidence for water now exists mainly in icy soil and thin clouds. Curiosity, a robotic rover about the size of a small SUV, is designed to find whether the Red Planet ever was -- or is still today -- an environment suitable for life. The rover landed on Mars in August 2012.

Jupiter Jupiter, the most massive planet in our solar system -- with dozens of moons and an enormous magnetic field -- forms a kind of miniature solar system. Jupiter does resemble a star in composition, but it did not grow big enough to ignite. The planet's swirling cloud stripes are punctuated by massive storms such as the Great Red Spot, which has raged for hundreds of years. Jupiter's appearance is a tapestry of beautiful colors and atmospheric features. Most visible clouds are composed of ammonia. Water vapor exists deep below and can sometimes be seen through clear spots in the clouds. The planet's "stripes" are dark belts and light zones created by strong east-west winds in Jupiter's upper atmosphere.

Saturn Adorned with thousands of beautiful ringlets, Saturn is unique among the planets. All four gas giant planets have rings -- made of chunks of ice and rock -- but none are as spectacular or as complicated as Saturn's. Like the other gas giants, Saturn is mostly a massive ball of hydrogen and helium. NASA's Cassini orbiter is on an extended mission to explore Saturn and its rings, its magnetosphere and its moons. Cassini also delivered Europe's Huygens probe to its historic landing on Titan in 2005.

Uranus Uranus is the only giant planet whose equator is nearly at right angles to its orbit. A collision with an Earth-sized object may explain Uranus' unique tilt. Nearly a twin in size to Neptune, Uranus has more methane in its mainly hydrogen and helium atmosphere than Jupiter or Saturn. Methane gives Uranus its blue tint. Most of what we know about Uranus came from Voyager 2's flyby in 1986. The spacecraft discovered 10 additional moons and several rings before heading on to Neptune.

Neptune Dark, cold and whipped by supersonic winds, Neptune is the last of the hydrogen and helium gas giants in our solar system. More than 30 times as far from the sun as Earth, the planet takes almost 165 Earth years to orbit our sun. In 2011 Neptune completed its first orbit since its discovery in 1846. Most of what we know about Neptune is thanks to Voyager 2's 1989 flyby. The spacecraft also discovered six of Neptune's moons.

Pluto Discovered in 1930, Pluto was long considered our solar system's ninth planet. But after the discovery of similar intriguing worlds deeper in the distant Kuiper Belt, icy Pluto was reclassified as a dwarf planet. This new class of worlds may offer some of the best evidence about the origins of our solar system. Pluto is also a member of a group of objects that orbit in a disc- like zone beyond the orbit of Neptune called the Kuiper Belt.
