Rouge Planets and Exoplanets

 Rogue planets are planets that do not orbit a star like the Sun. Instead, they travel through space on their own, either because they were ejected from their original solar system or formed independently in space. These planets are extremely difficult to detect because they do not reflect light from a star and are very cold and dark. Scientists believe there could be many rogue planets in our galaxy, drifting silently between stars.

Exoplanets are planets that orbit stars other than the Sun. They can be very different from the planets in our own solar system—some are giant gas planets larger than Jupiter, while others are small and rocky like Earth. Scientists have discovered thousands of exoplanets using telescopes by observing tiny changes in a star’s brightness when a planet passes in front of it. Studying exoplanets helps scientists learn whether other planets might have conditions suitable for life. Some exoplanets might be able to support human life.
