| | Lomonosov, Mikhail Vasilievich (1711-65) |
 | | In 1761, at the University Observatory in St Petersburg, Lomonosov observed a transit of Venus with the intention of finding the planet's diameter by measuring the size of its dark outline. |
 | | He was able to determine that Venus is similar in diameter to Earth, but the precision of his measurement was hampered by the fact that the edge of the planet's disk, instead of appearing sharp, as he'd expected, was fuzzy and indistinct. |
 | | Lomonosov was deeply impressed by Fontanelle's writings on pluralism and, in the face of opposition from the Eastern Orthodox Church, expressed his belief in many inhabited worlds in his native country. |
