What is the Environment of the Planet. What is the climate of
the Planet What type of Orbit the planet has speed/rotation type.
How far the planet is from the sun and how large/small the planet
is. Any special or unusual facts about the planet.
Slide 5
Earth is the third planet from the sun. Earth is the fifth
largest planet Earth surface: only planet with water on surface,
and 71% covered with water. Also composed of mountains, plains,
swamps and deserts. Orbital speed: 29.8 km/sec Climate: average
climate is 13 deg. C (55.4 deg F). Because of greenhouse effect
earths temperature is raised 35 deg. C (95 deg. F). Without
greenhouse effect earth would be a much colder planet, like Mars.
There is life on earth because there is the necessary gases for
life such as oxygen, hydrogen and a balance of carbon dioxide.
Earth also has a suitable climate for life.
Slide 6
Earths time is gradually slowing down. Every few yrs. a second
is added to make up for lost time, so that millions of yrs. From
now a day will be 27 hrs. long. Earth has existed for 150-200
million yrs. And life on Earth has only existed 5-10% of earths
lifetime. There is life on earth because there is the necessary
gases for life such as oxygen, hydrogen and a balance of carbon
dioxide. Earth also has a suitable climate for life.
Slide 7
Mars is known as the Red Planet because of its deep red color.
Orbit: Eliptical Atmosphere: Very thin, much like earth, only more
carbon dioxide and no greenhouse effect which makes it one of the
coldest planets, unlike earth. Climate: Much like earth only
seasons last 2X as long in martian yrs. In winter:Mars has polar
ice caps that will condense at night and evaporate into water vapor
in the day.
Slide 8
Special Facts About Mars There is evidence of many traces of
dried up water areas on Mars, such as dried up springs, gullies,
lakes and even photographic evidence of possible present bodies of
water. Because of Mars possibility of liquid water evidence and its
Atmosphere and climate simi- larities to earth scientists
hypothesize possible past life habitation and a favorable planet
for human habitation.
Slide 9
Saturn Second largest planet in the solar system and 6 th
planet from the sun. Orbital Speed: 9.7 km/sec. One day is 10hrs.
14mins and 1 yr is 29.5 earth days. Environment: Saturn is the only
planet that is less dense than water. Saturn is composed mostly of
gases, mainly hydrogen and small amt. of helium and methane.
Slide 10
Saturn Continued Climate: Wind blows at high speeds on Saturn
with velocity of 500m per sec. (1,100 mph). Special Facts Saturn
was first discovered to have 18 moons, but 4 more were found in
2000 and 9 more this yr. yielding a total of 31 moons. Saturns
rings are hypothesized to be particles of an old moon that had a
collision and smashed apart to pieces 50 mill. Yrs. Ago. Saturns
rings orbit in different tilts.
Slide 11
Jupiter 5 th planet from the sun. 740.3-815.7 million km away
from the sun. Largest planet in the solar system. It is11x wider in
diam. And 25x greater in mass, but1/4 less in density compared to
earth. Environment: Composed primarily of hydrogen (89%). Also,
helium (11%) and traces of methane, water vapor and ammonia. Orbit:
Speed: 778,330,000 km (5.20 AU from sun). Jupiter spins on its axis
and is the fastest rotating planet in our solar system. An earth
day on Jup. is 9.92 hrs. and 1 yr on Jup. Is equivalent to 11.86
days on earth. Climate: High dense pressure and temp. but avg.
temp. range is 130deg. C. at cloud tops and 30deg. C. below. Clouds
also cause Ultraviolet light, lightening, discharge and heat.
Slide 12
Special Facts About Jupiter There is a high pressure region of
clouds moving counter clockwise known as the Great Red Spot and it
stretches 12,000 by 25,000km in length and is possibly made of Red
phosphorus. The Rapid rotation of clouds on Jupiter causes belts
and zones that encircle the planet parallel to the equator. One of
Jupiters largest moons Europa is 3138km in diameter, and it is
covered in ice on its surface. Scientists say that under the ice
layer there may be liquid water, which may support life.
Slide 13
Venus Length from sun: 2 nd planet from the sun. Distance:
107.4-109 mill. Kms away from sun. Orbit: speed: 126,072 kmph, very
slow rotating planet. 1day=243 days on earth and 1yr= 225 days on
earth. Size: approximately the same size as earth. Known as earths
sister planet. (95% of earths diam, 80% of earths mass.
Environment: Hottest planet because composed mostly of (Co2)= (92%)
nitro-gen= 3.5%, and sulfuric clouds. It has green-House effect
because of (Co2). Climate: High temp, avg= (464deg. C). Because of
high temp and atmos- pheric pressure it is a hostile environment
for space probes and any life habitation.
Slide 14
Special Facts About Venus It has no rings and no moons Its
rotation is sychronized with earth so that the same face always
presents its self to earth when they are at their closest approach.
It is the brightest of all planets.
Slide 15
Pluto Pluto is the smallest planet. It is only 2300km wide in
diameter and has the smallest mass w/.0022 g/kg in density. Orbit:
Revolves on its axis, like Uranus, and at a 122.5 deg. Tilt. One
side of Pluto gets extreme periods of darkness. Distance from Sun:
Farthest planet from sun (3.67 bill. miles away), orbits with
Neptune around sun and it takes 6.39 days for a full rotation and
247.8 yrs. To revolve around the sun.
Slide 16
Planet Matching Game Which planet is the hottest? Which planet
has the fastest rotation? Which planet do we know the least about?
Which planet is the 2 nd largest planet ? Pluto Saturn Jupiter
Venus
Slide 17
Pluto Continued Environment: No space probes have succeeded to
land on Pluto, so not much is known about the planet (estimated to
happen 2015). It is observed to be a planet covered in ice like its
moon Charon. Climate:. Avg. temp. believed to be (-378/-396d.F)
Believed to be composed of primarily nitrogen (98%) and small amts.
Of methane and (C02). Special Facts: Many astronomers believe Pluto
is not a planet but either a star one of the 44 dwarf planets which
are planets scientists know of but have not named or studied. (More
Facts will be discussed)
