Space Powerpoint Overview
Rotation of the Earth
Earth rotation around the sun
Tilt of axis
Solar system (stars, sun, planet)
Gravity
The Sun.
What is space?
The physical universe beyond the
earth's atmosphere.
It consist of stars,planets,and
moons.
The apollo astronauts footprints
will stay there for about 100
million years.
Solar Systems
The Solar System is made up of all the
planets that orbit our Sun. The Solar
System also consists of moons, comets,
asteroids, minor planets, and dust and gas.
Everything revolves around the Sun.
The solar system was formed around 4.6
billion years ago.The four small inner
planets are Mercury,Venus,Earth, and Mars.
They are known as the terrestrial
plants.The four outer planets are
Jupiter,Saturn,Uranus,and Neptune.
They are also known as the Ice Giants.
The Sun
The sun accounts for 99.86% of
mass in solar system.
Over one million Earths could fit
inside the sun.
One day the sun will burn out.
The energy created by the Sun core
is nuclear fission.
The sun is almost a perfect sphere.
The sun is mostly composed of
helium.
Light from the sun takes eight
minutes to reach the earth.
Gravity
Every object in space has a gravitational pull. Gravity
influences the paths taken by everything traveling through
space. It is the glue that holds together entire galaxies. It
keeps planets in order.
The sun's gravitational pull keeps our planet orbiting the sun.
The moon's gravitational pull affects the earth's tides.
The Stars
Stars are cosmic energy that
produce heat, light, ultraviolet rays,
and other forms of radiation.
Stars are in perfect balance.
Most stars are red dwarfs.
Stars are made up of the same stuff.
The biggest stars are the shortest
lived
There are more than a billion stars in
the universe.
The Planets
A planet is a celestial body moving in
an elliptical orbit around a star.
Mercury, Venus, Earth, Mars,Jupiter,
Saturn, Uranus, Neptune. Pluto is
considered as a dwarf planet.
Tilt of Axis
Tilt of axis is the tilt of the Earth's
spin axis with respect to the plane of
its orbit about the sun . The Earth's
spin axis is tilted 23.5° with respect
to the ecliptic. As seen in the picture.
This gives us our seasons!
Rotation of The
Earth
Earth's rotation is the rotation of the
planet Earth around its own axis. The
Earth rotates from the west towards
east. As seen from North Star Polaris,
the Earth turns counter-clockwise.
Earth Rotation
Around The
Sun
As the Earth rotates, it also moves
around the Sun. The Earth's path
around the Sun is called a orbit. It
takes the Earth one year to
completely orbit the Sun. As the
Earth orbits the Sun, the Moon orbits
the Earth.
