6.Question 6Which of the following is NOT part of the explanation for why we continue to have near earth asteroids hit the earth even though the dynamical lifetime of a typical NEA is very short compared to the age of the solar system? (by dynamical lifetime we mean the time before it is likely to hit a planet or get ejected from the solar system) 1 pointAll of these are trueThe existence of families of asteroids formed by asteroid impact and shatteringHeating of small asteroids on one side coupled with rotation causing orbital driftResonances with Jupiter and Saturn in the asteroid belt leading to removal of objects in the asteroid beltOur improved technology which allows us to find ever-smaller near earth asteroidsThe high current eccentricities and inclinations of asteroids population leading to shattering impactsThe Yarkovsky effect

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.
