The
Solar System in which we reside is made up of the Sun, a medium-sized star, and
eight planets in orbit around it. There are two distinct sorts of planets.
Mercury, Venus, Earth, and Mars are the four inner planets, meaning they are
the ones nearest to the Sun. They are smaller and primarily made of rocks and
metals. Jupiter, Saturn, Uranus, and Neptune are the four outer planets; they
are larger and primarily made of gases.
The
solar nebula, around 4.6 billion years ago, a huge cloud of gas and dust
started to collapse in on itself, creating the solar system's sun and planets.
To ascertain the age of the solar system, scientists have employed meteorites,
or pieces of space rock that have fallen to Earth. Some of these minute pieces
that have broken off of planets or moons may provide important scientific
information about the composition and history of their parent body. Others have
been orbiting the sun since the formation of the solar system, far before the planets.
The oldest meteorite is 4.55 billion years old and came to Earth in the Allende
meteorite, which was dispersed over Mexico in 1969.
After
knowing all of this you got the feeling of looking at the photos of how the
solar system looks in real so here you can check the solar system planets
poster for your place to complete your fantasy about the solar system
and planets.
WHAT FORMED OUR SOLAR
SYSTEM?
Scientists
believe that the solar nebula collapsed as a result of a nearby supernova,
which is an exploding star. This hypothesis proposes that the explosion
generated shock waves that pushed the nebula's components closer together and
ultimately caused it to collapse. According to an earlier story from Live
Science, the supernova may have even seeded the nebula with the material. And
this is how the Solar system has been formed. Many people think that how our
solar system looks at an early time so for that also we have covered you with a
vintage
solar system poster which you can check on our website.
Modern Ideas for Solar
System
The
current theory on how the solar system formed views it as a component of the
larger process of star creation. The range of feasible hypotheses for this
process has shrunk as observational data have progressively increased. The
sources of this data range from studies of star-forming regions in massive
interstellar clouds to minor hints found in the chemical makeup of solar system
objects. Many scientists have contributed to the present viewpoint, but none
more so than American astrophysicist Alistair G.W. Cameron, who was born in
Canada.
Away From The Planets
The
Kuiper Belt and the Oort cloud are located beyond the ice giant Neptune in the
solar system. According to NASA, the Kuiper Belt is 30 to 55 astronomical units
(AU) wide, and its presence was established in 1992. (One AU, or 93 million
miles or 150 million kilometers, is the average distance between the Earth and
the sun).
Pluto
is the most well-known resident of the Kuiper Belt, but there are hundreds of
thousands of frozen objects there that are 62 miles (100 km) in diameter or
greater, many of which are relics of the early solar system, according to NASA.
