Read the passage and answer the following questions.MERCURYAmong eight planets in our Solar system, Mercury is the closest planet to the Sun and it needs only 88 days to complete an orbit around the Sun. According to Greek mythology, Mercury is the messenger of Gods (Hermes). Mercury is a small planer that bears a strong resemblance to the Moon with its little larger size rocky surface and many bowl-shaped cavities. Because of its position in the Solar system, the temperature on the sunny side of Mercury can reach over 800 degrees but -300 degrees is the other side’s temperature. Being cooler than only Venus, the hottest planet, the climate on Mercury is extremely severe which makes it hard to visit and explore. Two spacecraft have been sent to Mercury, the first was in 1974 and scientists had to wait three decades to visit Mercury the second time in 2004. Some people believe that there is no water in Mercury but some information collected from Radar showed that ice exists on the Northern pole of this planet. Small Mercury has no moons and no atmosphere because of its too little gravity (38% of the gravity of Earth). There is no report showing life's existence in Mercury yet.
