There are 8 planets within our solar system; they are
divided into 2 types, huge gas giants (Jupiter, Saturn, Uranus as well as
Neptune) and also smaller rocky terrestrial planets (Mercury, Venus, Earth and
Mars). An order from nearest the Sun outwards is; Mercury, Venus, Earth, Mars,
Jupiter, Saturn, Uranus and lastly Neptune. Until 2006 Pluto have also been
classed like a planet, Yet it's now classified as a dwarf planet (meeting the
initial two requirements with the definition however, not the third).
A planet happens to be defined by the IAU (International
Astronomy Union) as "a celestial body which (a) is within orbit around the Sun,
(b) has sufficient mass because of its self-gravity to get over rigid body
forces so it assumes a hydrostatic equilibrium (nearly round) shape, and also
(c) offers cleared the neighbourhood about the orbit."
Facts about Planet Earth
The Earth's rotation will be gradually slowing:
This deceleration is occurring almost imperceptibly, with
approximately 17 milliseconds per 100 Years, even though rate of which it takes
place isn't perfectly uniform.
1, The Earth once was considered to be the Centre from the
Because of the apparent movements with the Sun and planets
with regards to their viewpoint, ancient scientists insisted how the Earth
2. Earth includes a powerful magnetic field:
This phenomenon is brought on by the nickel-iron core with
the planet, along with its rapid rotation.
3. There is just one natural satellite from the planet
As a percentage of how big the body it orbits, the Moon will
be the largest satellite of the planet inside our solar system.
4. Earth will be the only planet not really named after a
Another seven planets within our solar system are named
after Roman gods or even goddesses.
5. Among all the planets within our solar system, the Earth
has got the greatest density:
This varies based on the part of the planet; as an example,
the metallic core is actually denser compared to crust
Facts About Mars the Planet
1. Mars is actually nicknamed the red planet because it's
covered with rust-like dust. Perhaps the atmosphere can be a pinkish red,
colored through tiny particles of dust thrown up from your surface.
2. Mars experiences violent dust storms which continually
change its surface.
3. Mars provides many massive volcanoes and is home to
Olympus Mons, the biggest volcano within our solar system, this stands 21km
high and it is 600km over the base.
4. Mars includes a very thin atmosphere created mostly of
carbon dioxide. It's not thick enough in order to trap the sun's heat such as
Venus; therefore the planet is extremely cold. Temperatures range between -120
Degrees Celsius upon winter nights to 25 Degrees Celsius in the summer.
5. Mars provides many channels, plains as well as canyons on
the surface which might have been due to water erosion in the past.
6. Mars has very weak gravity which usually cannot hold onto
the atmosphere well.
The polar ice caps contain frozen Co2 (dry ice) which lies
more than a layer of ice.
Facts About Dwarf Planets
1. You can find five official dwarf planets within our solar
system with another four objects that probably are. There are 394 objects
inside the solar system which are possible dwarf planets such as the five
2. The identified dwarf planets are usually Ceres, Pluto,
Haumea, Make's as well as Eris. These bodies are each more than appropriately
950 km in diameter.
3. All of the dwarf planets are based in the Kuiper Belt
with the exception of Ceres which can be found in the asteroid belt.
4. Absolutely no dwarf planets happen to be visited through
space probes, though in 2015 NASA's Dawn and also New Horizons missions can
reach Ceres as well as Pluto correspondingly.
