How do we track asteroids and comets?

Asteroids and comets are objects that travel through space, and tracking them is an essential task for astronomers and space agencies. There are several methods used to track asteroids and comets, including:

• Optical telescopes: These are the most commonly used instruments for tracking asteroids and comets. They can detect objects that reflect sunlight or emit their light, and can be used to determine an object's orbit, size, and shape.
• Radar: Radar can be used to track asteroids and comets that come close to Earth. Radar systems can determine an object's distance, speed, and size, and can also create images of the object's surface.
• Spacecraft: Spacecraft can be sent to visit asteroids and comets, and can provide detailed information about their composition, size, and shape.

By tracking asteroids and comets, astronomers can learn more about the history and composition of the solar system, and can also identify objects that could potentially pose a threat to Earth.
