Of course the sizes of objects are not to scale. Image: Representation of the inner solar system where each red dot represents one asteroid. Observations NEOWISE reduce by 40%, the actual number of near-Earth asteroids that exceed 100 meters. It can thus be compared to the old model, which estimates the visible were higher. The new model represents the coverage of NEOs is shown on the left of the image. they can come within 45 million km from Earth orbit. NEOs are asteroids and comets with orbits less than 1.3 AU, i.e. NEOWISE discovered 20 comets, more than 33,000 asteroids in the main belt between Mars and Jupiter, and 134 near-Earth objects (NEOs). Since February 2011, the NEOWISE NASA mission dedicated to research in the infrared small body, completed its quest on asteroids and comets in our solar system. Asteroids are of great importance in understanding the formation of the solar system, it is for this reason that astronomers show a strong interest in the study of these objects. Asteroids are remnants of the protoplanetary disk that failed to gather enough to form a planet during their formation. Objects less than 50 m in diameter are called meteorites. An asteroid is a celestial object in the solar system, not visible to the naked eye because of its small size, which varies from a few tens of meters to several hundred kilometers in diameter. It thus marks the boundary between the terrestrial planets and the gas giants. A significant portion of them circulate in a ring between the orbits of Mars and Jupiter, between 2 and 4 AU, called the asteroid belt. If the asteroid were "bright", we would see as much as stars in the night sky. Millions of small rocky bodies called asteroids are present in the solar system. Nota: Warning, more the objects are close to you and more they are big.

To view distances (million km), click the aphelion / perihelion button.Īlso play with the mouse: Clicking in the simulator gives you a hand to redirect the solar system and the desired view objects continue to revolve around the Sun. Approaching the perihelion (closest point to the Sun), objects accelerate at the approach of the aphelion (farthest point from the Sun), they slow down. Nota: You will notice that objects have different speeds, they respect the law of areas of Johannes Kepler (1571-1630).
With the arrows at the bottom right you can switch the orbital planes of asteroids and if you want more information, see the orbits more or less, use the buttons at the bottom left. You can zoom in (top right) to the inner solar system while leaving the asteroid rotated. Initially we are "above" the solar system (this is a view from the north celestial pole) and the passage of time is set to 10 days per second, which can see the planets rotate and asteroids in their orbits but you can go back in the future or in the past by using the buttons above. With this simulator you will see the revolution of asteroids from all angles and orbits located between Mars and Jupiter.
