An eye to our solar system||

What is our solar system

There are many planetary system like ours in the universe,with planet orbiting a host star.Our Planetary system is called solar system.

The solar system is the gravitationally bound system of sun and the object that orbit it,either directly or indirectly.

Here, the sun is our host star. It is orbited by all other planets. The sun is named Sol, after the Latin word for sun,"soils"and anything related to sun we called solar. So, because of it we call Solar system to our plantery system.

It is our solar system which is consist of star, the sun and everything bound to it by gravity. Among the objects there are planets, dwraf planets, millions of asteroids,comets and meteoroids.

The largest objects are the planets including Mercury,Venus,Earth,Mars,Jupiter, Saturn, Uranus and Neptune. And the smallest objects are the dwraf planets which orbit the sun indirectly

How old is our solar system

Through the help of scientists we can know the real age of our solar system. It was formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud.

From the meteorites or pieces of space rocks that have fallen to Earth the scientists have figured out the real age of our solar system.

The Allende meteorite, which fell to Earth in 1969 and scattered over Mexico, is the oldest known meteorite, dated to 4.55 billion years old.

We can also say that our solar system was formed from a dense cloud of interstellar gas and dust. The cloud was collapsed.

When this dust cloud collapsed, it formed a solar nebula—a spinning, swirling disk of material. Again according to the Wikipedia the real age of our solar system is 4.568 billion years old

Is there life in the solar system aside from on Earth?

We still don't have any evidence of life in the solar system aside Earth. But there are possibilities of life in the solar system in some place.

Scientists are trying to find the possibility of life in other planets and moons. Scientists thought that there is possibility of living in the Mars___ the planet next to Earth.

In our planet there are ocean, organic materials and mainly air which contains Oxygen are essential for lives.So, might we find life elsewhere in the solar system?

The possibility is too low. Because most of the planets and moons haven’t these necessary things for life, again if there is things it is not too much.Oceans were once thought to be unique to Earth, but now we know that water is found in several locations around our family of planets.

So it might be possible that there can be lives in our solar system aside from on Earth

Planets:

Under the influence of the gravitational ball, a number of astrologers orbit at a specific time, centering on a particular star, are called planets.

• They don't have their own light and heat.
• The eight planets of the solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune respectively.
