COMPARISON OF PLANET DISTANCES IN THE SOLAR SYSTEM FROM THE SUN
Astronomical Unit (A.U)
average distance between Earth and Sun - approx 150 mil km
1 A.U = 1.5 X 10(8) km
Light Years (ly)
distance travelled by light in a year
1 light year = 9.5 X 10(12) km
light moves 300 000km/second
PLANETS IN THE SOLAR SYSTEM AND ROTATIONAL DIRECTION
1)
Mercury
= 0.1º
2)
Venus
= 117º
3)
Earth
= 23º
most suitable for living things
4)
Mars
= 25º
5)
Jupiter
= 3º
6)
Saturn
= 27º
7)
Uranus
= 98º
8)
Neptune
= 30º
UNIT CONVERSION
between A.U and km
: DISTANCE (A.U) = DISTANCE (KM) / 1.5 X 10(8) KM
between LY and km :
DISTANCE (ly) = DISTANCE IN KM / 9.5 X 10(12) KM
CHARACTERISTICS OF PLANETS ARE INDICATED FROM :
natural satellite
= objects that move around the planet in their own orbit
relative mass, diameter and density
gravitational pull
surface temp and condition
distance from sun
rotation (time & velocity)
atmosphere
orbit
WHAT HAPPENS IF THE ROTATION OF EARTH STOPS/ SLOWS DOWN?
longer
day and night duration in two different parts of the world
more desert areas
temperature will drop
in parts that don't receive much sunlight
change in tides
