Which statement is not thought to be true of all comets in our solar system? Suppose there were no solar wind. Most comets have perfectly circular orbits. -It interacts with the solar wind and stimulates auroras. Geosphere B. What do asteroids and comets have in common? They are usually very hard to see, but as they approach the Sun these particles heat up and become much easier to see. Comets generally have elongated elliptical orbits. D) All asteroids lie in the asteroid belt between Mars and Jupiter. Normalize this equation using characteristic length $h$ (measured at $x=0$ ) and velocity $V$ (the average velocity).
