The gravitational perturbations of the other bodies of the Solar System cause a much smaller motion of the plane of Earth's orbit, and hence of the ecliptic, known as planetary precession. One month later, the sun would be flanked by the stars in Taurus, then Gemini, Cancer, Leo and so on. 30. A lunar eclipse happens when the moon passes through Earths shadow, when it is directly opposite the sun on the sky. [14], All of these expressions are for the mean obliquity, that is, without the nutation of the equator included. Autumn is the best time to see it before dawn.
