Amen. FORMATION OF STAR SYSTEM PREPARED BY : SIR GLEO  LEARNING OBJECTIVES At the end of the lesson , the students should be able to : Explain the Cite the Latest current developments advancement in the and information understanding of the solar of the system including Solar System the earth subsystem.  NEBULAR HYPOTHESIS The Nebular Hypothesis is a model that explains the formation and evolution of the solar system. The Nebular Hypothesis was first proposed by - Immanuel Kant and Pierre-Simon  NEBULAR HYPOTHESIS The temperature increase as the nebula collapsed The rotation increased with temperature The nebula eventually flattened into a disk. As the sun was forming in the center of the nebula, dust particles in the outer regions combined to form Planetesimals a few km across.  PLANETESIMAL AND TIDAL THEORY Planetesimal Theory focuses on the gradual buildup of planets from tiny particles within a nebula. Tidal Theory involves a dramatic event where a passing star's gravity pulls material from the Sun, which then forms planets. WHAT IS A STAR ?  STARS A star is a huge sphere of very hot glowing gas in space. When stars are grouped together we call them constellations. CLASSIFICATIONS OF STARS  CLASSIFICATIONS OF STARS The stars are classified according to : Temperature Brightness HOT STARS BLUE OR WHITE COOLER STARS RED, ORANGE & YELLOW YOUNG STARS Is called a dwarf star. They can be color red, yellow and white OLDER STARS Is called Super giants star They can be color red and blue  THE SUN The sun is the only star in our solar system. The sun is a yellow , medium sized star. IS THE SUN THE HOTTEST type of star?  IS THE SUN THE HOTTEST type of star? No, the Sun is not the hottest star there are many stars much hotter than the Sun, You can tell the approximate temperature of a star by looking at its color.  HOW STARS ARE BORN ? Stars are born in clouds of gas and dust called nebulae. Once a star has formed, it enters the main sequence phase, during which it spends most of its life. WHY DO STARS PRODUCE WHITE COLOR LIGHT ?  WHY DO STARS PRODUCE WHITE COLOR LIGHT ? Combination of Colors Stars produce white-colored light because they emit a mix of all colors of light. When you combine all these colors, they create white light. When all the colors blend together, they appear as white light to our eyes. WHY DO STARS TWINKLE ?  WHY DO STARS TWINKLE ? Because of the warm and cold air present in the atmosphere. Because of this disturbances in the path of light produced by the stars they seem to twinkle. WHAT ARE SHOOTING STARS ?  WHAT ARE SHOOTING STARS ? A shooting star is not a star that falls from the sky , it is just a misconception. The shooting stars are the meteoroids that burns when comes in the Earth’s atmosphere. HOW ARE STARS USEFUL ?  HOW ARE STARS USEFUL ? The stars are useful to the humans in many ways. The life source for all the living beings on earth They also tell us about the direction. Constellations CONSTELLATIONS  CONSTELLATIONS The stars forming a group that has a recognizable shape is called a CONSTELLATION. Four main types of constellations Ursa Major Cassiopeia Orion or Hunter Leo Major  URSA MAJOR, BIG DIPPER OR GREAT BEAR It is the constellation that is found at the early nights in summer. There are seven constant stars in this constellation. URSA MAJOR, BIG DIPPER OR GREAT BEAR  ORION OR HUNTER The orion is the constellation that can be seen during winter in the late evenings It has eight bright stars. The three stars in the middle show the belt of the Hunter. ORION OR HUNTER  CASSIOPEIA It is a prominent constellation seen in the northern sky during the winter in early night Story: In Greek mythology, Cassiopeia was a queen who bragged about her beauty. Cassiopeia is a constellation that looks like a big "W" in the sky. CASSIOPEIA  LEO MAJOR Leo Major, often just called Leo, is a constellation that looks like a lion. LEO MAJOR THE SUN THE SUN THE SUN  TERRESTRIALS GAS GIANTS  DAYS, YEARS AND SEASONS THE SUN THE SUN The center of the Solar System  OVERVIEW SUN Diameter: 1.4 million km (870,000 mi) Mass: about 1.989 x 10^30 kilograms Distance (Earth): 149.6 million kilometers Surface Temperature: 5,500°C Star Type: G-type main-sequence star Composition: The Sun is primarily composed of hydrogen (about 74% by mass) and helium (about 24%). Trace amounts of other elements, such as carbon, oxygen, and nitrogen, make up the remaining 2%.  THE PLANET MERCURY Our Sun's Closest Neighbor  OVERVIEW MERCURY Closest to the sun Smallest planet in our solar system Terrestrial Planet Length of Day: about 59 Earth days Length of Year: about 88 Earth days Hot during day and Cold during night No Moons. THE PLANET VENUS The Earth’s Sister Planet  OVERVIEW venus Second planet from the Sun Similar size to Earth Terrestrial Planet Length of Day: about 243 Earth days Length of Year: about 225 Earth days No Moons Called as the “ Morning Star” or the “Evening Star”. THE PLANET EARTH The Ever-Evolving Planet  OVERVIEW EARTH Third planet from the Sun Terrestrial Planet Supports life with air, water and Land Length of Day: 24 hours Length of Year: 365.24 days Consist of Oceans, continents, atmosphere. 1 Moon  THE PLANET MARS The Martian Red Planet  OVERVIEW MARS Fourth planet from the Sun Terrestrial Planet Mars is rocky, dusty and dry Length of Day: 24 hours and 39 minutes Length of Year: about 687 Earth days 2 Moons ( Phobos and Deimos )  Mars called as “ Red Planet “ The tallest mountain in the solar system can be found here , the “ Olympus Mons”  THE PLANET JUPITER The Giant Among The Giants  OVERVIEW JUPITER Fifth Planet from the Sun Gas Planet Distance (Sun): 778 million kilometers Distance (Earth): 365 million kilometers Length of Day: about 9 Earth hours Length of Year: about 11.86 Earth years 67 moons ( 4 Large Moons ) The largest moon in the solar system can be found here , the “Ganymede”. THE PLANET SATURN The Jewel of the Solar System  OVERVIEW SATURN Sixth Planet from the Sun Gas planet 7 flat rings made of Ice , rocks and Dust.
