Solar system

The Sun is a variable star, that is a big ball of glowing gas that evolves over time.

The proportion of iron in Mercury intrigue scientists.

Venus has a surface temperature of 470 ° C, the surface temperature is hot enough to melt lead.

The Earth is a miraculous blue dot, an oasis of life amid the vastness of a universe without end.

A huge collision between the young Earth and an object the size of Mars would have ejected from the field around the Earth, which would eventually form the Moon we see today.

Mars comes in like a star eyes blood red, this may be why it is called the god of war.

Phobos is so close to Mars at 9380 km, it can not be seen above the horizon at any point on the surface of Mars.

The gravity of Deimos is so small that a man escape from the satellite jumping, which is equivalent to an escape velocity of 10m/s.

Ceres is the largest and most massive object in the asteroid belt, its mass concentrated on its own third of the total mass of the asteroid belt.

Pallas est le deuxième plus grand astéroïde de la ceinture principale d'astéroïdes. L’objet serait selon des chercheurs américains, une protoplanète.

Juno, the small planet of 240 km in diameter was completely disfigured by a collision.

The asteroid Vesta is the brightest of all, it is named after the Roman goddess of health. This is the only asteroid visible to the naked eye.

Jupiter has 318 times the mass of the Earth, has acted as a shield, protecting life on our planet.

Ganymede, larger than Mercury, was discovered by Galileo in 1610, this moon of Jupiter has a surface dotted with craters brilliant.

Saturn rotates so fast in 10 hours that the centrifugal force forces the winds to blow parallel to the equator.

Titan is the only satellite in the Solar System to possess a thick atmosphere of nitrogen and methane clouds, in which one can observe a very active weather.

Uranus is composed of rock and ice, with only 15% hydrogen and some helium, while Jupiter and Saturn are composed almost entirely of hydrogen.

Titania has a huge canyon, much larger than the Grand Canyon on Earth, the same order of magnitude as Valles Marineris on Mars.

Neptune was not discovered by observation but with pencil and paper from the trajectory and characteristics of Uranus.

Triton is an external body, as captured by Neptune's orbit is retrograde, meaning that its direction is opposite to the rotation of Neptune.

The Kuiper Belt imagined in 1951 by Dutch astronomer Gerard Kuiper, extending from the orbit of Neptune (30 AU) to about 100 AU.

Pluto is not just a ball of ice and rock but a dynamic world undergoing dramatic atmospheric changes.

Eris is currently located at 97 AU from the Sun and rotates around it in 557 years, according to a orbit highly inclined about 44°.

Haumea is one of the largest members of a family called TNO (Trans-Neptunian Object), its dimensions are 1960 × 1518 × 996 km.

The Oort cloud is about 50 000 AU from the Sun, well beyond the Kuiper Belt, it contains billions of nuclei of comets of more than 1.3 km.
