Sam was gazing through a telescope and noticed a bright spot moving fast through the sky. On closer examination, he observed the spot was followed by a stream of dust as it neared the sun. What did Same most likely observe?(1 point) Responses A comet A comet a moon a moon An asteroid An asteroid A meteor
Sam most likely observed a comet. The key observations that indicate this are the bright spot moving through the sky and the stream of dust trailing behind it as it neared the sun. Comets are icy bodies that orbit the sun and as they get closer, the heat causes the ice to vaporize, creating a glowing coma (the bright spot) around the nucleus of the comet. The stream of dust is called a tail and it forms due to the solar wind pushing the vaporized material away from the comet. So, in this scenario, Sam most likely observed a comet moving through the sky.
