The Solar System
Transcript of The Solar System
Is the star in the center of the solar system.
It is almost perfectly spherical and consists of
hot plasma interwoven with magnetic fields.
It has a diameter of 1,392,684 km, around 109
times that of earth. Chemically, about three
quarters of the sun's mass consists of hydrogen,
while the rest is mostly helium. the remainder
consists of heavier elements, including oxygen.
carbon, neon and iron.
Its mass accounts for
about 99.86% of
the total mass
of the solar
Mercury is the smallest and closest to the sun
of the eight planets in the solar system, with an
orbital period of about 88 Earth days. Seen from Earth, it appears to move around its orbit in about 116 days, which is much faster than any other planet.
Does not have any moons around it.
The mass of this planet is 328.5E21 kg
(0.055 Earth mass)
Because Mercury orbits so close to the sun,
Its heavily cratered surface can reach
427 degrees Celsius. But without much
of an atmosphere to trap the heat,
nighttime temp. on Mercury
can plummet to -173
If one could stand on the scorching surface
of Mercury when it is at it's closest point
to the sun, the sun would appear almost
three times as large as it does when
viewed from Earth.
Is the second planet from the
sun, orbiting it every 224.7
Earth days. 108 million km is
the average distance from the
sun. The mass is 4.867E24 km,
bigger then Mercury, same size
as Earth. Distance from the sun
is 108,200,000 km. does not have
any moons around it.
After the moon, It is the
brightest natural object in the
sky, reaching an apparent
magnitude of -4.6, bright enough
to cast shadows.
Venus is a terrestrial planet and is
sometimes called Earth's "sister planet"
because of their similar size,
gravity, and bulk composition.
Is the third planet from the sun.
It is the densest and fifth-largest
of the eight planets in the solar
system. It is also the largest of the
solar system's four terrestrial planets.
It is sometimes referred to as the
world or the blue planet.
Earth's closest relative size
is Venus. Distance from the sun
is 149,600,000 km. Mass is
5.972E24 kg. The Earth rotates once
in about 24 hours with respect to the sun
and once every 23 hours, 56 minutes, and 4 seconds
with respect to the stars. Orbital takes 365 days. Earth has one moon.
Earth is the only planet in the solar
system to have water in its three states of
Earth is the only planet in the solar system
not to be named after a mythical god.
Mars is the fourth planet from
the sun and the second smallest
planet in the solar system.
Distance from the sun is 227,900,00 km.
The rotational period and seasonal cycles
of mars or likewise similar of Earth's, as is
the tilt produces the seasons. Its orbital period
is 687 days. Mars has two known moons,
Phobos and Deimos, which are small and irregularly
-befitting the red planet's bloody colour, the
Romans named it after their god of war.
- Mars is a terrestrial planet with a thin
atmosphere composed primarily of carbon
Jupiter is the fifth planet from the sun and
the largest planet in the solar system. it is
a gas giant with mass one-thousandth of that
of the sun but is two and a half times the mass
of all the other planets in the solar system
Mass: 1.898E27 kg (317.8
Distance from the sun: 778,500,000 km.
Orbital Period: 12 years
number of moons: found 23 in the year 2012
-The mass of Jupiter is 318 times the mass
of Earth. in fact, Jupiter has 2.5 times the mass
of all the other planets in the solar system
combined. but here's the funny thing...
If Jupiter got any massive, it would actually
get smaller. Additional mass would
actually make the planet more dense,
and start pulling it in on itself.
The atmosphere of Jupiter consists of
about 84% hydrogen and about 15%
helium, with small amounts of acetylene,
ammonia, ethane, methane, and water
Saturn is the sixth planet from the sun and the second largest planet in the solar system, after Jupiter. Saturn is a gas giant with an average radius about nine times that of Earth. It's interior is probably composed of a core of iron, nickel and rock, surrounded by a deep layer of metallic hydrogen, an intermediate layer of liquid hydrogen and liquid helium and an outer gaseous layer.
Distance from the sun is 1,433,000,000 km. Measuring the rotation of Saturn is actually a more complicated job than you might think. that's because that's because Saturn is just a ball of hydrogen and helium, without any solid features that you can measure from day to day. It takes 29 days to orbit around the suns atmosphere. Saturn has a total of 60 moons, many of which were only discovered in the last few years.
named after the Roman god of
agriculture, Saturn, it's astronomical

Saturn is the farthest planet from
Earth visible to the naked human
Uranus is the seventh planet from the
sun. It is the third-largest planetary
radius and fourth-largest planetary
mass in the solar system
Distance from the Sun- 2,877,000,000
km. Uranus revolves around the Sun
once every 84 Earth years and it has a rotational
period of 0.718 Earth days. Uranus has 27 moons.
Uranus's atmosphere, although similar to Jupiter's and Saturn's in it's primary composition of hydrogen and helium, contains more "ices" such as water, ammonia and methane, along with traces of hydrocarbons. it is the coldest planetary atmosphere in the solar system, with a minimum temp.
of -224.2 degrees Celsius.
Sir William Herschel announced it's discovery
on March 13, 1781, expanding the known
boundaries of the solar system for the first
time in history. Uranus was also the first planet
to be discovered with a telescope.
Neptune is the eighth and farthest planet from the Sun in the solar system. It is the fourth-largest planet by diameter and the third-largest by mass. Among the gaseous planets in the solar system, Neptune is the most dense.
Distance from the Sun: 4,503,000,000 km.
Neptune has a rotational period of 0.671 earth days and an orbital period of 164.79 earth years.
Neptune has 13 moons.
A Few Facts-
After Pluto was declassified as a planet, Neptune became the farthest planet from the sun. Neptune's diameter is about 30,200 miles or almost 4 time the earth's diameter. The planet was named after the Roman sea god.
Pluto is the only dwarf planet to once
have been considered a major planet.
Once thought of as the ninth planet
and the one most distant from the Sun.
Pluto is now seen as one of the largest
known members of the Kuiper Belt, a
shadowy disk-like zone beyond the orbit
of Neptune populated by a trillion or more
The distance from Pluto to the sun is 5,906,380,000 km. Pluto takes approximately 6.39 days to rotate on its axis. Pluto takes approximately 247.8 years to revolve around the Sun. Pluto has 5 moons.
The dwarf planet Pluto was named
after an ancient Roman god of the
underworld. In Roman mythology, Pluto
was the son of Saturn who, with his three
brothers, controlled the world. Jupiter controlled
the sky, Neptune controlled the sea, and Pluto controlled the underworld.
Pluto is the only well-known dwarf planet
with an atmosphere. It is very thin and would
be toxic for humans to breathe. When Pluto is at it's
perihelion (closest to the sun), Pluto's atmosphere is gas. when Pluto is at it's aphelion (farthest from the sun), it's atmosphere freezes and falls like snow.
Asteroids are small, airless rocky worlds revolving around the Sun that are too small to be called planets. they are also known as planetoids or minor planets. in total, the mass of all the asteroids is less than that of Earth's moon. but despise their size, asteroids can be dangerous. Many have hit Earth in the past, and more will crash into our planet in the future.

Meteors and meteoroids
can be anywhere in
space- they are the bits of
debris left over from the
formation of the planets and
the debris from the collisions
between asteroids and bits of
material ejected from comets.

When a meteor produces enough light to cast a shadow on earth it is called a fireball.
Ceres is a the largest asteroid and the only dwarf planet in the inner solar system.
Ceres is located among the the other asteroids in the asteroid belt between Mars and Jupiter.
Astronomer Giuseppe Piazzi discovered and named Ceres in early 1801. Though he classified it as a planet, Ceres is now classified as a dwarf planet which accounts for nearly 1/3 of the asteroid belt's mass.
Eris is the most-massive known dwarf planet in the solar system and the ninth-most-massive body known to directly orbit the sun.
Eris is located in the Kuiper belt beyond the orbit of Neptune.
Eris has one moon called Dysnomia.
A comet is an icy small solar system body that when passing close to the Sun, heats up and begins to out-gas, displaying a visible atmosphere or coma, and sometimes also a tail.
Comets contain dust, ice, carbon dioxide, ammonia, methane and more.
Meteorites are meteors that survives its passage though the Earth's atmosphere such that part of it strikes the ground. More than 90% of meteorites are of rock, while the remainder consists wholly or partly of iron and nickel.
These pieces of space rock can be found on Earth.
