Question

18 multiple choice 5 points which object in our solar system reflects light and is a satellite that orbits around one planet? earth mercury the sun the moon 19 multiple choice 5 points the milky way galaxy is best described as a type of solar system a constellation visible to everyone on earth a region in space between the orbits of mars and jupiter a spiral - shaped formation composed of billions of stars 20 multiple choice 5 points terrestrial planets move more rapidly in their orbits than the jovian planets because terrestrial planets are rotating on a tilted axis more dense more massive closer to the sun

Explanation:

• Question 18: The Moon is a natural satellite of Earth. It reflects sunlight (as it has no light of its own). Earth and Mercury are planets (not satellites orbiting one planet). The Sun is a star.
• Question 19: The Milky Way is a spiral - shaped galaxy. A solar system is a smaller unit (like our Sun - centered solar system). A constellation is a group of stars in a particular pattern. The region between Mars and Jupiter is the asteroid belt.
• Question 20: According to Kepler's laws of planetary motion, the closer a planet is to the Sun, the faster its orbital speed. Terrestrial planets (Mercury, Venus, Earth, Mars) are closer to the Sun than Jovian planets (Jupiter, Saturn, Uranus, Neptune). Rotation on a tilted axis affects seasons. Density and mass are not the main reasons for the difference in orbital speeds.

Answer:

1. the Moon
2. a spiral - shaped formation composed of billions of stars
3. closer to the Sun
