3. • The sun is the only star in the solar system. Also
it’s a medium size star. The sun is hot because
its atoms are constantly exploding with in it. Fuel
is always burning with in it. The sun is by far the
biggest mass in the solar system.
During a solar eclipse the
main part of the sun is
blocked off and only the
corona is visible.
5. Mercury is the closest planet to the sun and
the eight largest. It has a rocky body just
like earth. Even though it’s the closest
plant to the sun its not the hottest.
7. It’s a hot planet. Second closet planet to the
sun. It Has an extremely thick atmosphere
allowing it to contain more heat. Has the
exact characteristics as earth.
9. • As we all know it’s the planet we live on.
It’s the only planet in which there is more
water than land It’s the planet most
suitable for living. Its also the biggest inner
planet.
11. Mars is the fourth planet in the solar system.
The planet named after Mars, the Roman
god of war. Its Also called the Red Planet
because of its reddish appearance. It has
a thin atmosphere. It has water but only
deep into the planet. It has numerous
volcanoes.
13. Jupiter is the largest planet in our
solar system. Its mainly comprised of
gases. So you would find solid ground
there. One notable landmark of
Jupiter is the red spot, which is a
hurricane that has been going to tens
of thousands of years
15. Saturn is one planet amoungst the four
gas giants. Its mainly known for its
magnificent rings. Which in fact are only a
large collection of rocks and dust. It has
winds of up to 400mph!
17. Uranus is the 3rd planet in the gas
giants, its mostly known for having a
really tilted axis as you can see in the
picture in the back. Also it has rings but
so small they aren't noticeable
19. NEPTUNE known as the blue planet is the
most water filled planet in the solar system its
names after the Greek god Neptune king of
the sea. It also is a gas giant and is the
farthest planet from the sun.
21. Pluto is a dwarf planet and there is a
huge debate whether its an iceball
or a dwarf planet. It’s the farthest
object from the sun within our solar
system, little is known about it.
23. Difference between a Planet and Star
Stars are always much bigger than planets
Stars, grow big enough to spark nuclear fusion and planets
don’t.
Consequently, planets do not shine with their own light, but
reflect the light of a local star, and are cooler than stars.
Planets are less massive and therefore less dense than
stars.
stars are made of mostly hydrogen, which they push
together to form helium. this is then pushed together to
form other elements which are blown into space.
a star emits light produced by a nuclear reaction in its core,
whereas a planet only shines by reflected light.
24. In cosmogony,
the nebular
theory is the
most widely
accepted model
explaining
the formation and
evolution of the
Solar System. It
was first
proposed in 1734
by Emanuel
Swedenborg.Orig
inally applied only
to our own Solar
System, this
method of
planetary system
formation is now
thought to be at
work throughout
the universe.
25. The evidence supporting the nebula theory of Solar
System formation
1. All the planets orbit the Sun in the same direction. Most of
their moons also orbit in that direction, and the planets (and
the Sun) rotate in the same direction. This would be
expected if they all formed from a disk of debris around the
proto-Sun.
2.
26. 2. The planets also have
the right characteristics to
have formed from a disk of
mainly hydrogen around a
young, hot Sun. Those p
planets near the Sun have
very little hydrogen in them
as the disk would have
been too hot for it to
condense when they
formed. Planets further out
are mostly hydrogen,
(since that was what was
mostly in the disk), and are
much more massive
because there was so
much more material they
could be made from.
27. Difference between a planet and star
A star contains much more mass than a planet, enough that gravitational forces have compressed the
matter enough to start a fusion reaction at the nuclear level, radiating the resultant energy out.
. Also, their content is different. stars are made of mostly hydrogen, which they push together to form
helium. this is then pushed together to form other elements which are blown into space. (although one
star nicknamed lucy has got alot of carbon in its core, which because of the pressure has formed a
diamond which is a billion billion carats.) planets are different. although they may be made of gas, like
jupiter, they are different gases to the ones in stars. also, it is actually very unlikely that it is made
from gases. it is usually molten iron and rock.
A star is a burning mass of (mainly) hydrogen and helium. The outer planets are also made out of
hydrogen and helium. Neptune and Uranus theirs also have methane,hydrogen, and helium in it thats
why both planets are blue.
A planet is a body which moves in an orbit around a star.
A planet (of any sort, dwarf or other) is defined as "any celestial body which orbits a star." The earth is
a planet.
A star is typically a big, burning, ball of gas around which planets tend to orbit. (except when it goes
out, then it is a black hole or a neutron star.) The sun is a star.
