Exercise 9. Read the text and decide whether the sentence is true (T) or false (F).
Among the eight planets in the solar system, Mercury has achieved several "most" records:
Closest to the sun
The average distance between Mercury and the sun is 57.9 million kilometres, which is closer than other
planets in the solar system. Scientists haven't discovered any planets closer to the sun than Mercury so far.
•Maximum surface temperature difference
Because it is very close to the sun, the temperature of the sunny side on Mercury can reach 430°C at the
highest, but the night temperature on the back sunny side can fall to -160°CThe temperature difference
between day and night is nearly 600°C. This is the largest temperature difference between the planet's
surface.
Fastest year
The earth orbits around the sun every year, and the "Mercury year" is the shortest year in the solar system. It
takes only 88 days to go around the sun, which is less than 3 months on the earth. This is because Mercury is
flying around the sun at high speed. It also explains why the signs and symbols representing Mercury are
compared to a messenger wearing flying shoes and holding a magic wand, based on Greek mythology.
