Transits of Venus are very rare - two transits of Venus occur every 125 _______________________________. There have been only 52 transits of Venus across the Sun between 2000 B.C and A.D.1882. A transit of Venus lasts from 3 to 7 _______________________________; the exact time depends on the path taken across the Sun.

A transit is when a smaller body passes in front of a _______________________________ one (for example, when an object like Venus passes between the _______________________________ and the Sun). During a transit, the object (Venus in this case) appears as a small, dark object crossing the larger object. A transit is just like a special type of solar _______________________________, but the Sun does not go _______________________________; only a tiny bit of the Sun is obscured.

The only planets that ever pass between the Earth and the Sun are _______________________________ and Venus (since they are the only planets closer to the Sun than the Earth is).
