Space Facts for 6 Grade th Following are a series of slides related to our study of space. You are responsible for the definitions given you in class. You are also responsible for the material listed on the concept sheet. The links are for you to enjoy but will be gone over in class so arent required. The movie referenced below is 44 minutes long and detail 13 of the greatest Astronomy discoveries of all time.

Earth The Earth is the third planet in order from the sun,having an equatorial diameter of 7926 miles (12,755 km) and a polar diameter of 7900 miles (12,714 km), a mean distance from the sun of 92.9 million miles (149.6 million km), and a period of revolution of 365.26 days. Earth has one satellite, the moon. http://www.youtube.com/watch?v=lwwioJhQzeg
hemisphere A hemisphere is half of the terrestrial globe or celestial sphere, especially one of the halves into which the earth is divided. Southern Hemisphere Northern Hemisphere
Eastern Hemisphere Western Hemisphere http://www.youtube.com/watch?v=DYwA_8qMt9I axis An axis is a line about which a rotating body, such
as the Earth, turns. equinox An equinox is one of two date(s) at which the axis of the sun is directly parallel the sun. March 21 and Sept 21. Equinoxes are days in which day and night are of equal duration. The two yearly equinoxes occur when the
Sun crosses the celestial equator. solstice A solstice is one of two date(s) at which the axis of the sun is pointed directly toward or away from the sun. June 21 and December 21 The solstices are days when the Sun reaches its farthest northern and southern declinations. The winter
solstice occurs on December 21 or 22 and marks the beginning of winter (This is the shortest day of the year in the northern hemisphere.). The summer solstice occurs on June 21 and marks the beginning of summer (This is the longest day of the year. In the northern hemisphere).
seasons Seasons are changes in climate (temperature, water, etc.) caused by the position of the Earths axis due to receiving different amounts of the suns energy as the Earth revolves around the sun http://www.youtube.com/watch?v=DuiQvPLWziQ tide Tides are the periodic rise and fall of the waters of the ocean and its inlets, produced by the attraction
of the moon and sun, and occurring about every 12 hours. http://www.mmscrusaders.com/newscirocks/ti des/tideanim.htm sun The sun is a glowing ball of plasma a yellow star. The sun contains 99.86% of the mass of the solar system. It is over
99% hydrogen with 1% helium. The Sun is a yellow dwarf star. solar eclipse A solar eclipse occurs when the moon comes between the sun and a point on the earth. http://www.youtube.com/watch?v=O-X4QmWpjBM Solar Eclipse Educational Videoby kohjb51,639 views star
A star is a massive, luminous sphere of plasma held together by gravity. (plasma a hot glowing ball of gases. The HertzsprungRussell diagram is a scatter graph of stars comparing their brightness (absolute magnitude) and temperature (which causes their color). H-R diagrams are not pictures or maps of the locations of the stars. Instead,
they plot each star on a graph measuring the star's absolute magnitude or brightness against its temperature and color. the moon The natural satellite of Earth, visible by reflection of sunlight and having a slightly elliptical orbit. Apollo 11 was the spaceflight which landed

250,000 miles from Earth. Earth Saturn has more than 30 moons. has one moon that stabilizes Why do we only see one side of the moon? Watch this video.

During a total lunar eclipse, the moon appears to be red and is still visible. http://www.youtube.com/watch?v=DU-mW-qy4PU&feature=related rotation A rotation is the act or process of turning around a center or an axis: the axial rotation of the Earth is responsible for night and day and the day length. http://

constellation A constellation is a group of stars given a name by group of people. the hunter Ursa Major the great bear the scorpion the swan
constellation: Ursa Major (the big bear) North Star Polaris http://www.allthesky.com/constellations/ursamajor/ The name "The Great Bear" seems to have been assigned to the constellation in antiquity, due to its northern latitudes. Only a prodigious
bear could live in such a northerly clime. constellation: Cassiopeia Cassiopeia is a constellation in the northern sky, named after the vain queen Cassiopeia in Greek mythology, who boasted about her unrivalled beauty. Cassiopeia was one of the 48 constellations listed by the 2nd century Greek astronomer Ptolemy, and it remains one of the 88 modern constellations today. It is easily recognizable due to its distinctive 'W' shape, formed by five bright stars. It is bordered by Andromeda to the south, Perseus to the southeast, and Cepheus to the north. She is opposite the Big Dipper, and from northern latitudes can be seen at her
clearest in early November. constellation: Scorpius (the scorpion) Scorpius is one of the oldest constellations known possibly even one of the original six signs of the zodiac. Gaia sent the scorpion to kill Orion. The animal would chase Orion across the heavens, but it could never catch him, for the scorpion was so placed that it would rise in the east only after Orion had safely disappeared over the western horizon.
constellation: cygnus (the swan) Several extrasolar planets including HAT-P-7b, HAT-P-11b, HD 185269 b, HD 187123 b and c, Gliese 777 b and c, and 16 Cygni Bb, have been discovered in Cygnus, but the most notable is Kepler 22b, which is believed to be the first "Earth-twin" planet ever discovered, with an estimated average surface temperature of 73 degrees Fahrenheit. constellation: Orion The middle star in Orions sword is actually a nebula, a
star that went nova In 1054. Orion is one of the most well-known constellations, visible in the southern sky during northern hemisphere winters. He is generally shown as a hunter attacking a bull with an upraised club, and is easily recognizable by his bright belt of three stars. In addition, his shoulder is marked by the red supergiant Betelgeuse (literally "armpit of the central one" in Arabic), and his left leg is marked by the blue-white supergiant Rigel. According to the versions of the myth which have him killed by Scorpius, the two were placed on the opposite sides of the sky from each other so that they are never visible at the same time.
