Question
Which statement about asteroids is not true?Group of answer choicesTheir images become blurry due to outgassing as the Sun heats them up.Most stay between the orbits of Mars and Jupiter.They vary considerably in composition, reflectivity, and size.Earthgrazers can cross not only our orbit, but even those of Venus and Mercury.Some have satellites of their own.
Solution
The statement about asteroids that is not true is: "Their images become blurry due to outgassing as the Sun heats them up." This is actually a characteristic of comets, not asteroids. When comets get close to the sun, the heat causes ices in the comet's nucleus to vaporize and create a cloud called a coma around the nucleus, which can make their images appear blurry. Asteroids, on the other hand, are made up of rock and metal and do not have this outgassing effect.
