Bats use SONAR (Sound Navigation & Ranging).Sonar is a technique that uses sound propagation to navigate, communicate with or detect objects on or under the surface of the water, such as other vessels.
Impact crater is a type of impact landform formed due to collision of astronomical objects. Impact crater is a circular depression formed by the hypervelocity impact of a smaller body. Impact craters should not be confused with landforms like sinkholes, glacial cirques which are different in composition and origin from the impact crater.
Asteroids also called the inner solar system are minor planets which are neither categorised as a planet or a comet. They are in direct orbit around the Sun. They primarily remain on the circumstellar disk of gas around new stars and also the debris of the disk together. They are also known as planetoids and range in size from hundreds of miles to few feet. Most of them are irregular in shape. They are majorly present in the asteroid belt between Mars and Jupiter.
