What is the transit of Venus? The transit of Venus can be observed on June 6, 2012

What is a transit of Venus? The orbit of Venus is inside the orbit of the Earth. At certain special moments, the Earth, Venus and the Sun will be in a straight line. At this time, from the Earth, Venus can be seen moving slowly on the surface of the Sun like a small black dot. Astronomy calls this "transit of Venus." The transit of Venus can be observed on June 6, 2012!

The orbit of Venus is inside the orbit of the Earth. At certain special moments, the Earth, Venus and the Sun will be in a straight line. At this time, from the Earth, Venus can be seen moving slowly on the surface of the Sun like a small black dot. Astronomy calls this "transit of Venus." The most anticipated astronomical phenomenon in 2012, the "Venus Transit", will take place on June 6. Astronomical experts said that this is the last time it will be visible until 2117. The transit will last for 6 hours and most parts of my country are in the best observation area.

The duration of Venus transits is usually measured in hours (in 2004 and 2012, they lasted about 6 hours). The principle is similar to a solar eclipse, although Venus' diameter is almost four times that of the Moon. When we look at Venus from Earth, it is much smaller than when Venus transits the Sun.

Because it is farther away from the earth. Before modern astronomy, people used parallax to measure the distance between the Sun and the Earth by observing the transit of Venus.
