-
                                                         
 If you are thinking that you know all about our solar system here some facts are available, you should have to know these facts about our solar system. Let's start our journey of the solar system.

1) Our solar system is 4.5 billion years old



Our solar system is ancient. The age of our solar system is nearly 4.568 billion years old. If the timeline of the universe we measure on cosmos calendar, humans come only some second before in the universe.

2) A day is longer than a year on Venus

Venus is the second planet from the sun and the second-brightest natural object in the night sky after the moon. A day is how long it takes a planet to rotate fully, and a year is how long a planet takes to orbit the sun, isn't it..? We all know that The Venus is one of only two planets that rotate clockwise, and it spins much slower than others in the solar system. It takes 243 Earth days to do a complete rotation and 225 Earth days to orbit the sun. This fact is really mind-blowing. Therefore, A day is longer than a year on Venus.


3) The Pluto isn't the only dwarf planet we have...!

We all know that pluto is a dwarf planet but, here Pluto isn't only a dwarf planet in our solar
system. There are five currently officially classified dwarf planet in our solar system. They
are Ceres, Pluto, Haumea, Makemake, and Eris.


4) The sun accounts 99.8%  mass of the entire solar system...!

  You ever imagined, how big the sun is...?  The radius of the sun is 696,340 km. The sun is
864,400 miles across. This is about 109 times the diameter of Earth.

5) What about Uranus? you can't stand on Uranus.

 We all know Uranus as a gas giant. If we ever plan to go on a trip on Uranus, You will be
shocked when you reach your location because you can't land your spaceship on Uranus.
Uranus has no solid surface to land on it.

6) Saturn's rings are made 90% of water

Saturn is famous because of his beautiful rings and the second biggest planet in our solar
system. The Saturn is too far from the sun so the water in it rings is frozen into ice. Saturn's
surface is mainly like the Uranus surface.

7) There are194 moons,  3,583 comets, and 796,289 asteroids had been found in our sola

 system.

8) The sunset on The mars appears blue

 This sounds impossible and beautiful too, but this is true. Mars has not a perfect atmosphere
like the earth that's why the sunset from mars is blue in color. This effect called Rayleigh
scattering. This effect caused by the presence of 1% by volume of magnetite in the dust particles.

9) Saturn's moon Titan has liquid oceans of natural gas.

Saturn's moon Titan has lakes and oceans of liquid methane and ethane that has been detected by the Casino-Huygens space probe and has been suspected long before. The large ones are known as maria(seas) and the small one as locus(lakes).

10) Pluto is smaller in diameter than the U.S. 

The greatest distance across the contiguous united states from northern California to Maine is nearly 2,900 miles(4,700 km). But the pluto is 1,473 miles across, less than half the width of the U.S.

                                                       Photo by  NASA  on  Unsplash The Sun is 400 times larger than the moon but is 400 times further away from earth. That's the thing making them appear the same size. If you ever stepped on the moon, your footprints would remain there forever. Because of less friction on the moon's surface. How big the sun is ?...1 million earth can fit insides the sun. The Sunset on Mars appears blue. The furthest manmade object is Voyager -1. It has messages for aliens on board in many different languages. Saturn would float if you put it in water. Because the density of Saturn is less than the density of water.  1 year on Mercury consists of less than two days of Mercury. 1 day of mercury consists of 58 days:15 hour:30 minutes of earth. Every year, the moon is moving away from earth by 3.8 centimeters. The light-emitting from the sun is 30,000 years old. Our solar system is 4.57 billion year old. The highest mountain discove

"MATHEMATIC" most students hate this subject, I don't know why. But mathematic is a truth and we can't replace it with another. Today I'm going to tell you some crazy and unknown facts about mathematic.  These facts are commonly based on casual mathematic, concepts of "Possibilities" and also concepts of "Permutation and Combination". Math formula 1) Multiplying 21978 by 4 reverses the order of the number: 87912, And also     Dividing 87912 by 4 reverses the order of the number: 21987 2) 2,520 is the smallest number that can be divided by all the numbers 1 to 10.             3) There are 177,147 ways to tie a tie, according to Mathematicians. 4) The largest prime number ever found is more than 22 million digits long. 5) Multiplying 1089 by 9 the answer be = 9801 6) Students who chew gum have better math test scores than those who don't. This was founded in a study. So let's start to chewing gum. 7) I

All of us using AI in our daily life like Google, Alexa, Siri, etc. Also, Jarvis is an AI. We all know Jarvis and Ultron in movies. Before some time we can't imagine the world based on AI, But today we are working with them. So let's know them. What exactly Artificial Intelligence? AI is an area of computer science that emphasizes the creation of machines that work and react like humans. AI works by combining large amounts of data with fast, iterative processing and intelligent algorithms, allowing the software to learn automatically from patterns or features in the data. It provides human-like thinking ability to these AI and this process is too interesting. There are 4 types of AI is available:   1)Reactive machines 2)Limited machines 3)Theory of mind 4)Self-awareness There are 3 types of AI by generation: 1)Narrow or weak AI 2)General or strong AI 3)Artificial superintelligence   We have currently only achieved 1st gene
