Super Blue Moon A super blue moon combines a supermoon and a blue moon. A supermoon occurs when the moon aligns closely with Earth during its orbit, making it appear larger and brighter. This alignment, called perigee, contrasts with apogee when the moon is farthest in its elliptical orbit around Earth. While the difference is subtle, near the horizon, an optical illusion can make it seem larger. Hence, statement 1 is correct.
A blue moon is the second full moon in a month. Despite its name, a blue moon isn't blue; it's the traditional name for the second full moon in a month. Hence, statement 2 is not correct.
Sometimes, smoke or dust in the air can scatter red wavelengths of light, as a result of which the moon may, in certain places, appear more blue than usual, but this has nothing to do with the name “blue” moon. Blood Moon: A blood moon occurs during a total lunar eclipse when the Earth aligns between the Moon and the Sun, casting a shadow on the Moon. Hence, statement 3 is correct.
Only the red-tinted light refracted by Earth's atmosphere reaches the Moon's surface, giving it a reddish glow. The term "blood moon" can also refer to a reddish Moon caused by atmospheric conditions or autumn foliage.
