Solar Eclipse Of March 9, 1997
A total solar eclipse occurred on Sunday, March 9, 1997. 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. Totality was visible in eastern tip of Kazakhstan, northern tip of Xinjiang and Northeastern China, Northern Mongolia and Russia. Unusual gravity variations This solar eclipse is somewhat special in the sense that some unexplained gravity anomalies of about 7 \times 10−8 m/s2 during the solar eclipse were observed. Attempts (e.g., Van Flandern–Yang hypothesis) to explain these anomalies have not been able to reach a definite conclusion. Images Related eclipses Eclipses ...

Solar Eclipse
A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby obscuring the view of the Sun from a small part of the Earth, totally or partially. Such an alignment occurs during an eclipse season, approximately every six months, during the new moon phase, when the Moon's orbital plane is closest to the plane of the Earth's orbit. In a total eclipse, the disk of the Sun is fully obscured by the Moon. In partial and annular eclipses, only part of the Sun is obscured. Unlike a lunar eclipse, which may be viewed from anywhere on the night side of Earth, a solar eclipse can only be viewed from a relatively small area of the world. As such, although total solar eclipses occur somewhere on Earth every 18 months on average, they recur at any given place only once every 360 to 410 years. If the Moon were in a perfectly circular orbit and in the same orbital plane as Earth, there would be total solar eclipses once a month, at every new moon. Instead, because the Moon ...

March 1997 Lunar Eclipse
A partial lunar eclipse took place on Monday, March 24, 1997, the first of two lunar eclipses in 1997. This partial lunar eclipse was nearly total; however, it occurred 3 days after the lunar apogee, so the umbral shadow is smaller. This was the 29th member of Lunar Saros 132, and the last of the first set of partial eclipses. The next event was the April 2015 lunar eclipse, which was the first of 12 total eclipses. This eclipse was the third of an ''almost tetrad'' (that occurred when there were 4 consecutive lunar eclipses that had an umbral eclipse magnitude of 0.9 or greater). The others were 04 Apr 1996 (T), 27 Sep 1996 (T) and 16 Sep 1997 (T). Visibility This eclipse was completely visible from North and South America, and visible setting over Western Europe and Africa.

March 1997 Events
March is the third month of the year in both the Julian and Gregorian calendars. It is the second of seven months to have a length of 31 days. In the Northern Hemisphere, the meteorological beginning of spring occurs on the first day of March. The March equinox on the 20 or 21 marks the astronomical beginning of spring in the Northern Hemisphere and the beginning of autumn in the Southern Hemisphere, where September is the seasonal equivalent of the Northern Hemisphere's March. Origin The name of March comes from '' Martius'', the first month of the earliest Roman calendar. It was named after Mars, the Roman god of war, and an ancestor of the Roman people through his sons Romulus and Remus. His month ''Martius'' was the beginning of the season for warfare, and the festivals held in his honor during the month were mirrored by others in October, when the season for these activities came to a close. ''Martius'' remained the first month of the Roman calendar year perhaps a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Comet Hale-Bopp
A comet is an icy, small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process that is called outgassing. This produces a visible atmosphere or coma, and sometimes also a tail. These phenomena are due to the effects of solar radiation and the solar wind acting upon the nucleus of the comet. Comet nuclei range from a few hundred meters to tens of kilometers across and are composed of loose collections of ice, dust, and small rocky particles. The coma may be up to 15 times Earth's diameter, while the tail may stretch beyond one astronomical unit. If sufficiently bright, a comet may be seen from Earth without the aid of a telescope and may subtend an arc of 30° (60 Moons) across the sky. Comets have been observed and recorded since ancient times by many cultures and religions. Comets usually have highly eccentric elliptical orbits, and they have a wide range of orbital periods, ranging from several years to potentially several milli ...

September 1997 Lunar Eclipse
A total lunar eclipse took place at the Moon's descending node of the orbit on Tuesday, September 16, 1997, the second of two lunar eclipses in 1997. A shallow total eclipse saw the Moon in relative darkness for 1 hour, 1 minute and 30.8 seconds. The Moon was 19.094% of its diameter into the Earth's umbral shadow, and should have been significantly darkened. The partial eclipse lasted for 3 hours, 16 minutes and 28.2 seconds in total. The penumbral eclipse lasted for 5 hours, 8 minutes and 20.1 seconds. The partial eclipse lasted for 3 hours, 16 minutes and 28.2 seconds. The total eclipse lasted for 1 hour, 1 minute and 30.8 seconds. Maximum eclipse was at 18:46:39.1 UTC. The moon's apparent diameter was extremely large (6.3% larger than average) because occurred only 3 hours and 21 minutes past perigee. The Moon was only 356,986 km (221,820 mi) of the Earth at greatest eclipse. This eclipse was the fourth and last of an ''almost tetrad'' (that occurred when there were 4 consecuti ...

Solar Eclipse Of September 2, 1997
A partial solar eclipse occurred on Tuesday, September 2, 1997. 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 partial solar eclipse occurs in the polar regions of the Earth when the center of the Moon's shadow misses the Earth.

Moon
The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of Australia). The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at , with Jupiter's moon Io being the only satellite in the Solar System known to have a higher surface gravity and density. The Moon orbits Earth at an average distance of , or about 30 times Earth's diameter. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day. The Moon's orbit around Earth has a sidereal period of 27.3 days. During each synodic period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
