The transit of Venus has been observed by astronomers since 1639. As reported by the Moscow media house Glas Rusia, famous Russian scientist Mikhail Lomonosov (1761-1711) observed Venus at the Petrograd Observatory in 1765.
Based on observations, Lomonosov stated that Venus has an atmosphere, which turned out to be correct.
The orbits of Earth and Venus are inclined to each other at a certain angle.
The transits appear in the same pattern every 243 years, two occur in winter with an eight-year break, then a long period of 121,5 years, and two in summer - with an eight-year interval, followed by a period of 105,5 years.
The last summer transit of Venus was on June 8, 2004.
