What makes asteroid different from other objects in space?

Here are a few ways that they differ: Asteroids aren’t all round like planets. They have jagged and irregular shapes. Some asteroids are hundreds of miles in diameter, but many more are as small as pebbles.

What are the distinguishing characteristics of an asteroid?

Nearly all asteroids are irregularly shaped, although a few of the largest are nearly spherical, such as Ceres. They are often pitted or cratered — for instance, Vesta has a giant crater some 285 miles (460 km) in diameter. The surfaces of most asteroids are thought to be covered in dust.

How is an asteroid different from a planet?

Asteroids are smaller than a planet, but they are larger than the pebble-size objects we call meteoroids. For example, some asteroids orbit the Sun in a path that takes them near Earth. Most asteroids in our solar system can be found in the asteroid belt, between Mars and Jupiter.

What force formed the solar system?

gravity
Solar system formation began approximately 4.5 billion years ago, when gravity pulled a cloud of dust and gas together to form our solar system.

Which of the following is a characteristic of an asteroid that can be defined from a light curve?

A rotating asteroid shows a light-curve amplitude of zero (no change in amplitude) when its shape is a uniform sphere or when it is viewed along one of its rotational axes.

What are the factors that make the planet habitable?

What Are the Factors that Make the Planet Habitable?

• It has to be a comfortable distance away from a star (Habitable Zone)
• The stars around it have to be ‘stable’.
• It should not have a very low mass.
• It must rotate on its axis and revolve.
• It should have a molten core.
• It should hold an atmosphere.

What is nebula theory?

The nebular hypothesis is the idea that a spinning cloud of dust made of mostly light elements, called a nebula, flattened into a protoplanetary disk, and became a solar system consisting of a star with orbiting planets [12].

What are observational characteristics of an eclipsing binary star?

Eclipsing binary stars are just one several types of variable stars. These stars appear as a single point of light to an observer, but based on its brightness variation and spectroscopic observations we can say for certain that the single point of light is actually two stars in close orbit around one another.
