How do scientists explain the location of the asteroid belt?

Most asteroids orbit the sun within a broad belt located between the orbits of Mars and Jupiter: the asteroid belt. While most asteroids are located in the main belt, asteroids can be located throughout the solar system. Those with orbits that carry them close by Earth are known as Near-Earth Asteroids (NEAs).

How do we locate asteroids?

Asteroids reflect sunlight just like the planets do, this means that with a suitable telescope we can see asteroids from the Earth. When we take pictures of asteroids from the Earth with a telescope we typically get images that look like the one below.

How do scientists think the asteroid belt formed for kids?

A long time ago, in the early stages of the Solar System, rock and dust circling the Sun were joined into planets. Some believe that the gas giant Jupiter or other big planets contributed to the destabilization of a forming planet, which resulted in the asteroid belt.

What is the Kuiper belt and where is it located?

The Kuiper Belt is a region of space. The inner edge begins at the orbit of Neptune, at about 30 AU from the Sun. (1 AU, or astronomical unit, is the distance from Earth to the Sun.) The outer edge continues outward to nearly 1,000 AU, with some bodies on orbits that go even further beyond.

Where is the asteroid belt located in the atmosphere?

The Main Belt lies between Mars and Jupiter, roughly two to four times the Earth-sun distance, and spans a region about 140 million miles across.

Why is it important that scientists track the locations and movement path of asteroids?

But there is another reason studying asteroids and their movements is important: detecting nearby asteroids and predicting any hazard they might pose to Earth. Both 2014 JO25 and Bennu are considered near-Earth objects, meaning their orbits bring them closer than 1.3 astronomical units (AU) from the sun.

Why do scientists study asteroids?

The biggest reason as to why we study asteroids is because they can tell us about the origins of the Solar System, as they are considered to be the building blocks of the planets. In planetary formation, lumps of rock, such as asteroids, coalesce to create minor planets and eventually planets.

Are asteroids found in the Kuiper Belt?

The Kuiper Belt is a disk-shaped collection of asteroids (inset diagram) that floats within the far larger, spherical Oort Cloud of comets. Over the past 26 years, the number of Kuiper Belt objects (KBOs) found has grown to more than 1,000.

Where is the asteroid belt located in the solar system?

There are lots of asteroids in our solar system. Most of them are located in the main asteroid belt – a region between the orbits of Mars and Jupiter.

Where is the asteroid belt located?

Where is the main asteroid belt in the solar system located?

Mars
Main Asteroid Belt: The majority of known asteroids orbit within the asteroid belt between Mars and Jupiter, generally with not very elongated orbits. The belt is estimated to contain between 1.1 and 1.9 million asteroids larger than 1 kilometer (0.6 miles) in diameter, and millions of smaller ones.

How does NASA detect and track asteroids?

One of the ways that NASA detects and tracks asteroids is with a space telescope called NEOWISE. The spacecraft uses infrared to detect and characterize asteroids and comets. Since December 2013, NEOWISE has discovered 72 near-Earth objects and characterized 439 others.

How close can an asteroid be to the Earth?

While that’s a safe distance, it’s close enough that the asteroid will come between Earth and our Moon, which is about 238,855 miles (384,400 kilometers) away. It’s also within the distance that some spacecraft orbit Earth.

Why is the study of asteroids important?

The study of asteroids is so important, in fact, that NASA has sent several spacecraft to study some of these objects up close. For example, in 2007, the Dawn mission was sent to explore the two largest objects in the asteroid belt, Vesta and Ceres.

Why do comets and asteroids come close to Earth?

Some asteroids and comets follow orbital paths that take them much closer to the Sun — and therefore Earth — than usual. If a comet or asteroid’s approach brings it to within 1.3 astronomical units of the Sun, we call it a near-Earth object.
