Which is the difference between asteroids and comets?1. Asteroids are small rocky planetoids, while comets are formed of frozen gases held together by rocky and metallic material.2. Asteroids are found mostly between the orbits of Jupiter and Mars, while comets are found mostly between Venus and Mercury.3. Comets show a perceptible glowing tail, while asteroids do not.Which of the statements given above is/are correct?
✓ Correct answer: b) 1 and 3 only
ExplanationStatement 1 is correct: Asteroids are primarily composed of rock and metal and are remnants from the early solar system.In contrast , Comets are made of ice, dust, and rocky material and originate from the Kuiper Belt or Oort Cloud.Statement 2 is incorrect: Asteroids are predominantly located in the asteroid belt between Mars and Jupiter.Comets originate from distant regions of the solar system: short-period comets come from the Kuiper Belt beyond Neptune, and long-period comets originate from the distant Oort Cloud.They are not typically found between Venus and Mercury.Statement 3 is correct: As comets approach the Sun, the heat causes their icy components to sublimate, forming a glowing coma and often a visible tail that points away from the Sun due to solar wind.Asteroids, being rocky and lacking volatile materials, do not exhibit such features.122
