● The Sun’s corona is the outermost part of the Sun’s atmosphere . Hence, Statement 1 is correct . ◦ The corona is usually hidden by the bright light of the Sun’s surface. ◦ 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.
