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 ...

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] |
Earth
Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More solar e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Eclipse Of May 11, 1975
A partial solar eclipse occurred at the Moon's descending node of the orbit on Sunday, May 11, 1975. A solar eclipse occurs when the Moon passes between Earth and the Sun The Sun is the star at the center of the Solar System. It is a nearly perfect ball of hot plasma, heated to incandescence by nuclear fusion reactions in its core. The Sun radiates this energy mainly as light, ultraviolet, and infrared radi ..., 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.

May 1975 Lunar Eclipse
A total lunar eclipse took place on Saturday, May 24 and Sunday, May 25, 1975, the first of two total lunar eclipses in 1975. The Moon was plunged into darkness for 1 hour and 28 minutes in a deep total eclipse which saw the Moon 43% of its diameter inside the Earth's umbral shadow. The visual effect of an eclipse depends on the state of the Earth's atmosphere, but the Moon may have been stained a deep red colour. The partial eclipse lasted for 3 hours and 35 minutes in total. Occurring only 4.4 days after perigee (Perigee on May 20, 1975), the Moon's apparent diameter was 0.7% larger than average. The moon was 377,010 km (234,263 mi) from the Earth at greatest eclipse. The eclipse was a dark one with the southern tip of the moon passing through the center of the Earth's shadow. This was the first central eclipse of Saros series 130. Visibility It was completely visible over North and South America, seen rising over Australia on the evening of Sunday 25 May 1975, and setting ...

November 1975 Lunar Eclipse
A total lunar eclipse took place on Tuesday, November 18, 1975, the second of two total lunar eclipses in 1975. A shallow total eclipse saw the Moon in relative darkness for 40 minutes and 11.1 seconds. The Moon was 6.421% of its diameter into the Earth's umbral shadow, and should have been significantly darkened. The partial eclipse lasted for 3 hours, 29 minutes and 2.1 seconds in total. Occurring only 4.9 days after apogee (Apogee on Friday, November 14, 1975), the Moon's apparent diameter was 4% smaller than average. Visibility It was completely visible over eastern North America, eastern South America, Europe, Africa and Asia, seen rising over the Americas and setting over Asia and the Indian Ocean.
