How do scientists predict asteroids?

Most asteroids are discovered by a camera on a telescope with a wide field of view. This predicts approximate positions over the next few nights and follow up can then be carried out by any telescope powerful enough to see the newly detected object.

How do you create an orbit?

Orbits are the result of a perfect balance between the forward motion of a body in space, such as a planet or moon, and the pull of gravity on it from another body in space, such as a large planet or star.

How long is the orbital period of an asteroid?

3 to 6 years
Most of them occupy a great ring, known as the asteroid belt, at mean distances of 2.2 to 3.3 AU from the Sun and with orbital periods of 3 to 6 years.

What technology is used to study asteroids?

The traditional way to study asteroids, and the way asteroids are discovered, is by using optical telescopes. Click on the image at right to find out more. In the last few decades radar telescopes have proven to be a very powerful method for imaging selected asteroids from Earth.

What tools are used to study asteroids?

Radio telescopes such as Arecibo or Goldstone have been used to observe asteroids. This technique can be used to measure the Doppler shifts and radar cross-sections of the bodies, while more detailed studies allow three-dimensional shape models to be built.

When will the sun explode?

Scientists have conducted a lot of researches and study to estimate that the Sun is not going to explode for another 5 to 7 billion years. When the Sun does cease to exist, it will first expand in size and use up all the hydrogen present at its core, and then eventually shrink down and become a dying star.

What is the period of an orbit?

The orbital period (also revolution period) is the time a given astronomical object takes to complete one orbit around another object, and applies in astronomy usually to planets or asteroids orbiting the Sun, moons orbiting planets, exoplanets orbiting other stars, or binary stars.
