What is solar system short note?
The Solar System is made up of all the planets that orbit our Sun. In addition to planets, the Solar System also consists of moons, comets, asteroids, minor planets, dust and gas. The inner solar system contains the Sun, Mercury, Venus, Earth and Mars. The main asteroid belt lies between the orbits of Mars and Jupiter.
What is solar system for kids?
The Solar System is made up of the Sun and all of the smaller objects that move around it. Apart from the Sun, the largest members of the Solar System are the eight major planets. Nearest the Sun are four fairly small, rocky planets – Mercury, Venus, Earth and Mars.
What are 5 facts about the solar system?
Interesting Facts About the Solar System
- The definition of a planet and a moon is fuzzy.
- Comets and asteroids are leftovers.
- The planets are all on the same “plane” and orbit in the same direction.
- We’re nowhere near the center of the galaxy.
- But the Solar System is bigger than you think.

What are the lines in the solar system?
In astronomy or planetary science, the frost line, also known as the snow line or ice line, is the particular distance in the solar nebula from the central protostar where it is cold enough for volatile compounds such as water, ammonia, methane, carbon dioxide, and carbon monoxide to condense into solid ice grains.
What is the solar system answer?
The Solar System is the Sun and all the objects that orbit around it. The Sun is orbited by planets, asteroids, comets and other things. The Solar System is about 4.6 billion years old. It formed by gravity in a large molecular cloud.
How large is our solar system in light years?
1.50 light years
How old is our solar system?
4.571 billion years
How long is the solar system?
Well, it depends a bit on how you define the “end.” If you choose Pluto, the outermost planet, as the end, then the diameter of the solar system is 80 A.U. A.U. means “astronomical unit”; then the distance between Earth and the sun equals miles. So that would be 7,(over seven billion) miles.
How are solar systems formed?
Formation. Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula—a spinning, swirling disk of material.
Does planet9 exist?
Unless Planet Nine is observed, its existence is purely conjectural. Several alternative hypotheses have been proposed to explain the observed clustering of TNOs….Planet Nine.

What is the name of the new planet?
Researchers have discovered a new Earth-sized planet orbiting a star outside our solar system. The planet, called Kepler-1649c, is only around 1.06 times larger than Earth, making it very similar to our own planet in terms of physical dimensions.

What Colour is water?

Why the sea is blue?
The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. The ocean may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water.
Which water is safe drink?
Use bottled water or a different source of water if you know or suspect that your water might be contaminated with fuel or toxic chemicals. In emergency situations, use bottled water if possible; bottled water is the safest choice for drinking and all other uses.
What is the Colour of Earth?
Explanation: Here are the true colors of planet Earth. Blue oceans dominate our world, while areas of green forest, brown mountains, tan desert, and white ice are also prominent. Oceans appear blue not only because water itself is blue but also because seawater frequently scatters light from a blue sky.
