21st April Lesson title: Space Celestial objects Key Words Lesson Objectives: Astronomy State the difference between a comet and an asteroid. Star Planet Moon Asteroid Comet Galaxy
Astronomy What words do you think of when you hear the word Astronomy ? Astronomy is the study of the universe beyond the Earth s atmosphere.
Celestial Bodies A celestial body is a naturally made object outside the Earth s atmosphere. We shall look at some of these bodies in our universe now..
Planets M V E M J S U N Planets orbit around a star
Moon Moons orbit planets Earth has one moon A moon is a natural satellite of a planet Later we shall look at other planets in our solar system and the number of moons they each have..
Stars A star generates its own light and heat It s a big ball of burning gas! Hottest stars are blue, coldest are red Moons orbit planets Planets orbit stars. Stars are spherical in shape not star shaped.
Asteroids An asteroid is a small rocky object that orbits a star, but is too small to be considered a planet They are irregular in shape Found between the orbits of Mars and Jupiter the asteroid belt
Comets A comet is a small object made up of frozen gases, ice, rock and dust that can glow and produce a tail They orbit the sun When they come close to the sun they heat up and glow
Galaxies A galaxy is a large group of stars, dust, gas and dark matter held together by gravity They can be different shapes but most are spiral Solar systems make galaxies. Galaxies make up the Universe.
Our Solar System Our solar system is a group of planets, asteroids, comets that are in orbit around a star and held together by the star s gravity. Planets and stars make up solar systems.
Planet Data What do you think happens the surface temperature the further you move away from the planets? Celestial Bodies Sun Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Time taken to travel around the sun (days/years) n/a Surface Temp (oC) Distance from the sun (million kms) 0

Planet Data What do you think happens the surface temperature the further you move away from the planets? We can now conclude the temperature decreases!

Dwarf Planets A dwarf planet is a round space object that circles a star but has not cleared its own orbit They do not have enough gravity to pull the smaller objects in. Can you think of an example of a dwarf planet?
Using the information youve gathered, plot a graph of surface temperature [y] against distance from sun [x]: 500 400 300 Surface Temp. [C] 200 100 0 0 1000 2000 3000 4000 5000 6000 7000 -100 -200 -300 Distance from Sun [Million km]

Earth Facts Earth has a tilt angle about 23.5o relative to its orbit plane. It takes Earth 365 days to orbit the sun. The moon orbits the Earth every 28 days approx. This causes phases.
