2002 in science

A total solar eclipse occurred at the Moon's descending node of orbit on Wednesday, December 4, 2002, with a magnitude of 1.0244. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. Occurring about 1.9 days after perigee (on December 2, 2002, at 8:50 UTC), the Moon's apparent diameter was larger.

An annular solar eclipse occurred at the Moon's ascending node of orbit between Monday, June 10 and Tuesday, June 11, 2002, with a magnitude of 0.9962. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Occurring about 6.4 days after apogee (on June 4, 2002, at 14:00 UTC), the Moon's apparent diameter was smaller.
