What is a lunar eclipse?
A lunar eclipse is when the order is the Sun, Earth and then the Moon in the Earth’s shadow. There can be a partial lunar eclipse or a total lunar eclipse depending on where the earth is on its orbit. It also matters where the moon is, whether at apogee (its farthest position from the earth) or at perigee (the closest to the Earth). The lunar eclipse this Friday, 27th July, is a blood moon meaning that the moon will appear red. The red hue is as a result of scattering of the sun’s light as it passes through the earth’s atmosphere, this is call Rayleigh scattering. If a lunar eclipse occurs when the moon is at perigee it called a super moon lunar eclipse. This is because the moon appears larger than usual when it is in this position. It can also be referred to as a super blood moon.
