Some interesting facts about the solar system
Solar system
which we can call our home, it is our identity in space
with the help of which we are recognized in the entire Milky way galaxy.
There are many solar systems in the universe,
but our solar system is very different from all other solar systems.
It is believed that the origin of the Solar system
was around 4.5 billion years ago and the sun was formed during this process.
The Solar system
includes the sun and the celestial bodies that are connected to each other with
the help of gravitational force. The Solar system
includes the sun, planets, natural satellites, meteorites, rock planets and comets,
while the sun is a star in its center. It acts as a source of energy and light
for the bodies of the Solar system.
Apart from that, there are many facts
about the Solar system
that we should know about.
Fact #1
At the edge of the Solar system
there are small massive bodies that we call comets.
They are formed from rocks, soil, frozen gas. Like the Earth,
comets
also revolve around the Sun. As they orbit the Sun, they become extremely hot,
ejecting gas and dust that creates a glowing tail of light.
It is believed that there are many comets
in the solar belt. They are also considered ice compounds because they are
formed by mixing frozen gas and water. It is also said about them that they are
balls of gas that could not become planets. When they are close to the sun,
they can be seen clearly. For a long time,
they remain hidden. While some comets
are visible when the Earth passes close to their revolving orbit. Many of them
are seen regularly.
Fact #2
The group of celestial bodies orbiting around
a star is called a planetary system. Other non-stellar objects such as planets,
asteroids, meteors, celestial bodies, celestial rocks, comets
and celestial dust.
The Sun and its planetary system together form
our Solar system.
99.56% of the mass of the Solar system
is contained in the sun
.
Fact #3
The Solar system
consists of eight planets including Mercury, Venus,
Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Although earlier it included
the name of Pluto, but in 2006 it was excluded from the list of planets. Now
Pluto is known as a Dwarf Planet. As the Sun rotates,
its orbit collides with the orbit of Neptune, so it is rejected as a planet.
Fact #4
Because of the Solar system,
we know that volcanoes exist on other planets and moons.
These volcanoes are much larger than Earth's
volcanoes. Some of them are inactive which have not erupted for many years and
may not erupt in the near future but some are active like volcanoes on Earth.
Fact #5
We all know that there is only one Solar system
in the universe
in which we live, but scientists estimate that there are one hundred billion Solar systems
in our Milky Way Galaxy.
Galileo made physical details about the individual bodies of the Solar system.
Fact #6
There is a region in our Solar system
called the Asteroid Belt. This belt is located between Mars and Jupiter. It has
thousands of celestial stones orbiting around the Sun. There are about a
million celestial bodies in our Solar system,
but most of them are too small to be seen from Earth.
Each celestial body has its own orbit in which it revolves around the Sun. The
largest of them is the Ceres series. Most of the rotating
celestial bodies are made of rocks and stones, which also contain some iron and
nickel.
Fact #7
It takes 8 minutes and 20 seconds for sunlight
to reach Earth.
Actually, the Earth
is located at a distance of 15 million kilometers or 9.3 million miles from the
Sun. Light
emitted from the sun travels at the speed of light.
The speed of light
is three hundred thousand kilometers per second or 186,000 miles per second.
Fact #8
Generally, the temperature of a planet varies
with its distance from the sun. In this sense, Mercury is the closest planet to
the Sun, but did you know that Venus,
instead of Mercury, is considered the hottest planet in the Solar system
because of its thick carbon dioxide atmosphere? Mercury is hotter than Jupiter.
Mercury creates a greenhouse gas effect. Mercury's atmosphere is much cooler
than that of Venus,
so it cannot absorb the heat of the Sun easily.
Fact #9
Earth
takes one year to complete one cycle around the Sun and a year is 365 days but
did you know that Mercury completes one cycle around the Sun in 88 Earth
days, While Neptune takes 165 Earth
years to complete one cycle.
Fact #10
The Sun, the star at the center of our Solar system
that is the most important source of energy for life on Earth,
is approximately 109 times
the size of Earth.
If we talk about the weight of the sun, its mass is 1.98x10^30 kg, which is
about 333,000 times
more than the mass of the Earth.
It is so big that 13 million Earth-like
planets can fit inside it. The surface temperature of the Sun is about 5505 degrees
Celsius and it is 4.6 billion years old.
The Sun is a ball of hot gases composed mainly
of hydrogen and helium. Proxima Centauri is the closest star to the Sun. Only a
small fraction of the energy emitted by the sun reaches the Earth,
15% of which is returned to space,
30% is used to make water vapor, and most of the energy is absorbed by plants
and oceans.
