AstronomyAstronomy is the study ofmoons,planets,stars,nebulae, andgalaxies, and the physics,chemistry,mathematics, andevolutionof objects, that begin outside of theatmosphere of Earth. It also includes supernovae explosions,gamma ray bursts, andcosmic background radiation.

AstronomyAstronomy is one of the oldest sciences. Prehistoric cultures left behind astronomical artifacts that proved theyperformed observations of thenight sky.However, the invention of thetelescopewas required before astronomy was able to develop into a modern science.

AstronomyHowever, the invention of thetelescopewas required before astronomy was able to develop into a modern science.During the 20th century, the field of professional astronomy split intotwo branches. One branch focuses on observations, the other focuses on the physics of the stars. Amateur astronomers, people who use astronomy as a hobby, have made important discoveries.

RotationEarth's rotationis therotationof theEartharound its own axis. The Earth rotates from the west towards theeast. If you look at the earth from the North Star or Polaris, the Earth turns counter-clockwise.

RotationThe North Pole is different from the magnetic North Pole. TheSouth Poleis the other point where the Earth's axis of rotation intersects its surface, inAntarctica. The Earth rotates once in about 24 hours.

Define Rotation:

Define Revolution:PlanetAplanet is anastronomical objectorbitingastarand is big enough to have its owngravity.The term planetis ancient, with ties tohistory,science,mythology, and religion. The planets were originally seen by many early cultures as divine, or as Gods.

PlanetAs scientific knowledge advanced, human perception of the planets changed. In 2006, theInternational Astronomical Union(IAU) officially adopted a resolutiondefining planetswithin theSolar System. This definition has been both praised and criticized and remains disputed by some scientists because it excludes many objects ofplanetary massbased on where or what they orbit.

PlanetEight of the planetary bodies discovered before 1950 remain "planets" under the modern definition. Planets are divided into two main types: large, low-densitygas giantsand smaller, rockyterrestrials.

Planet Object that orbits a star Big enough to have its own gravity As knowledge of planets changed, we chose to have only 8 planets PlanetRound object made of gas or rock Big enough to have its own gravity Orbits the sun 8 planets in our solar system StarAstaris a huge, luminous sphere of gas held together by its own gravity. The nearest star to Earthis theSun, which is the source of most of our planet's energy. Some other stars are visible from Earth during the night.

StarHistorically, the most prominent stars were grouped intoconstellations. Constellations are groups of stars that appear to form a pattern in the night sky. The biggest stars were given names. Stars have lives that begin in a collapse of gas called a nebula and end in an explosion called a supernova

StarsStars are made of Helium (He) and Hydrogen (H)There are over 40 billion stars in our galaxy Stars are born in nebula and die in a supernova Solar System TheSolar System is made of the sun, eight planets, and all objects that orbit the sun. Our solar system was formed 4.6 billion years ago. There is an inner solar system that includes Mercury, Venus, Earth, and Mars. There is also an outer solar system Jupiter, Saturn, Uranus, and Neptune. The asteroid belt separates the inner and outer solar systems.

The Moon is in synchronous rotationwith Earth, always showing the same face. It is the brightest object in the sky after the Sun, although its surface is actually dark. Its prominence in the sky and its regular cycle of phaseshave, since ancient times, made the Moon an important cultural influence onlanguage, calendars,artand mythology

Moon. The Moon's gravitational influence produces theocean tides. The Moon is thought to have formed nearly 4.5 billion years ago, not long after the Earth. The Moon is the onlycelestial bodyother than Earth on which humans have set foot. The Moon remains, under theOuter Space Treaty, free to all nations to explore for peaceful purposes.

The lunar phases change cyclically as the Moon orbitsthe Earth. The half of the moon surface facing the Sun is always sunlit, but the portion of this illuminated hemisphere that is visible to an observer on Earth can vary from about 100% (full moon) to 0% (new moon). Phases of the Moon All parts of the Moon see around 14.77 days of sunlight followed by 14.77 days of "night. Thefour major phases of the moonare called the new moon, first quarter moon, full moon and last quarter moon.
