◦ That makes it difficult to see without using special instruments.
● However, the corona can be viewed during a total solar eclipse . Hence, Statement 2 is correct .
● The corona is about 10 million times less dense than the Sun’s surface. Hence, Statement 3 is correct .
◦ This low density makes the corona much less brighter than the surface of the Sun.
