Kepler´s laws of planetary motion
The three important laws describing planetary motion were formulated by Johannes Kepler.
Kepler, planetary motion, focal point, ellipse, radius vector, orbital period, planet, Solar System, gravity, circulatory system, mechanics, astronomy, astronomer, physics
The Kepler space telescope was launched by NASA to discover Earth-like planets orbiting other stars
This animation shows optical and radiotelescopes used in astronomical observation
This animation introduces the studies of astronomers and physicists whose works fundamentally changed our view of the universe.
The orbits of the 8 planets in our Solar System are elliptical.
A wide variety of optical instruments are in use today, ranging from microscopes to telescopes.
The inner planets of the Solar System are terrestrial planets while the outer planets are gas giants.
A spacecraft on its path is in a constant state of free fall.
Comets are spectacular celestial bodies orbiting the Sun.
The Earth is a rocky planet with a solid crust and oxygen in its atmosphere.
This animation presents some interesting facts in the field of astronomy.
The International Space Station is a habitable satellite built with the cooperation of 16 countries.
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
The largest satellite of Pluto is Charon.
Satellites orbiting the Earth can be used for civilian or military purposes.
Saturn is the second largest planet in the Solar System, easily recognisable by its rings.
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 diameter of the Sun is about 109 times that of the Earth. Most of its mass consists of hydrogen.
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 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 April 12, 1961.
Massive accelerating or orbiting bodies cause ripples in spacetime. These are called gravitational waves.
The Hubble Space Telescope orbits outside the distorting influence of Earth´s atmosphere.
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).
Nuclear fusion will serve as an environmentally friendly and practically unlimited source of energy.
