Q&A

• What do asteroids, comets, and meteors have in common?

  Asteroids, comets, and meteors all orbit the sun, coming in different sizes and compositions. While asteroids are small rocky objects, comets are made of ice and dust. Meteors are generated when meteoroids enter Earth's atmosphere, creating a breathtaking visual display.

• How do large asteroids avoid bombarding inner planets?

  Large asteroids would bombard inner planets if not for Jupiter's gravitational pull. This significant statement serves as an example of the pivotal role that Jupiter plays in maintaining the stability of the solar system.

• What are the roles of meteors and asteroids in space?

  Meteors produce a sonic boom when they become visible, while asteroids are rocky or metallic objects that orbit the sun, coming in various sizes and shapes. Ceres, once classified as the largest asteroid, is now considered a dwarf planet.

• What determines the color of meteors?

  Meteors' color depends on metallic content and superheated air plasma. Moreover, meteoroids are objects in space, meteors are in the atmosphere, and meteorites are when the object hits the ground.

• How could a comet have caused the extinction of dinosaurs?

  A comet may have caused the extinction of dinosaurs through a chain of disastrous events. Additionally, meteors, or meteoroids burning up in the Earth's atmosphere, create visible light, also known as shooting stars.

• How do comets form tails and what is their origin?

  Comets enter huge elliptical orbits, losing material when close to the sun, and forming tails due to the solar wind. The heat of the sun melts the ice of the comet, turning it into gas and forming a coma. Most comets are thought to originate from a huge cloud called the Oort cloud.

• What is the folklore surrounding comets?

  The folklore surrounding comets depicts traditional beliefs about their significance and appearance, often reflecting cultural interpretations and historical perspectives on these celestial phenomena, adding a rich dimension to their study.

• What do comets and asteroids reveal about the origins of the solar system?

  Comets and asteroids provide valuable clues about the origins of the solar system, shedding light on its formation and early history, offering crucial information for scientists to better understand the celestial bodies in our system.

• What have recent advances in space technology enabled in the study of comets and asteroids?

  Recent advances in space technology have enabled interdisciplinary collaboration in the study of comets and asteroids, allowing scientists from various backgrounds to work together to gain insights into the origins of the solar system.
