The life-cycle of the Solar System
The formation of the Sun and the planets started with the contraction of a dust cloud about 4.5 billion years ago.

A demonstration of nearby planets, stars and galaxies.
The inner planets of the Solar System are terrestrial planets while the outer planets are gas giants.
The orbits of the 8 planets in our Solar System are elliptical.
The diameter of the Sun is about 109 times that of the Earth. Most of its mass consists of hydrogen.
Comets are spectacular celestial bodies orbiting the Sun.
The diameter of our galaxy is about 100,000 light years; it contains more than 100 billion stars, one of which is our Sun.
This animation demonstrates the process of star development for average and massive stars.
The Earth is a rocky planet with a solid crust and oxygen in its atmosphere.
Jupiter is the largest planet of the Solar System, it has two and a half times the mass of all the other planets combined.
Possible traces of water and life are sought on Mars.
Mercury is innermost and smallest planet of the Solar System.
Neptune is the outermost planet of the Solar System, the smallest of the giant planets
During its orbit around the Earth, the visibility of the Moon's illuminated part constantly changes.
The largest satellite of Pluto is Charon.
Saturn is the second largest planet in the Solar System, easily recognisable by its rings.
The Moon is the Earth's only natural satellite
Uranus is the 7th planet from the Sun, a gas giant.
Venus is the 2nd planet from the Sun, the brightest object on the night sky (after the Moon).
The Earth's continents have been in constant motion during the history of the planet.
The Hubble Space Telescope orbits outside the distorting influence of Earth´s atmosphere.
The International Space Station is a habitable satellite built with the cooperation of 16 countries.
Lunar eclipses occur when the Moon passes through the shadow cone of Earth
Space probes and Mars rovers examine the structure of Mars and possible traces of life.
The Space Shuttle was a manned, reusable spacecraft operated by NASA.
The Soviet-made satellite was the first spacecraft to be launched into outer space (in October 1957).
The Cassini spacecraft was exploring Saturn and its moons for nearly 20 years.
Studying Ceres and Vesta will help us learn more about the early history of the Solar System and how rocky planets are formed.
The New Horizons space probe was launched in 2006, with the objective to study Pluto and the Kuiper Belt.
The Voyager space probes were the first man-made objects to leave the Solar System. They gather data about outer space and carry information about humanity.
Yuri Gagarin became the first human in space on 12 April 1961.
The animation shows the two-seater Lunar Rover used in the Apollo 15 mission
Neil Armstrong, one of the crew members of Apollo 11 was the first man to set foot on the Moon.
When the Sun, Earth, and the Moon are arranged in a straight line, the Moon can partially or completely obscure the Sun.
