10 Interesting Facts about Solar System

“When you look at the stars and the galaxy, you feel that you are not just from any particular piece of land, but the solar system.” –Kalpana Chawla, Astronaut

The interesting facts about the solar system contain that it is a group of objects that interact with one another. All objects in the solar system orbit around the Sun and they move in elliptical paths. The fundamental force that keeps objects revolve around Sun in a particular orbit is gravity. In terms of mass, the fact about the solar system is that the Sun composed 99.8% of the Solar System’s total weight. 

 Surprising Facts About the Solar System

The following are some interesting facts about the solar system.


  • Pluto Has Mountains

Earlier, scientists thought that Pluto is a dwarf planet that has a stable environment. Some recent discoveries show that Pluto has icy mountains, with a height of 11,000 feet or 3,300 meters high. 

  •  Smaller Bodies Can Also Have Moon

As a fact about the solar system, most people used to think that only large objects like planets have moons or natural satellites. But Galileo discovered that even asteroids have moons. For instance, asteroid Ida has a one-mile-wide moon named Dactyl. 

  • Hottest Planet Isn’t Close to the Sun

Venus is more humid than Mercury. Since Venus has a thick carbon dioxide layer, which creates a greenhouse effect. Its average temperature is about 468 degrees Celsius.

  •  Mercury is Shrinking

In 2016, MESSENGER spacecraft reported that Mercury has cliff-like landforms known as fault scarps. Since they are relatively small, thus, scientists claim that Mercury is shrinking. 

  • There Could Be Life Somewhere

Till now, scientists have not found any evidence that there could be life somewhere else in the solar system. But they have discovered microbial life on Mars. 

  •  Tilted Uranus

Uranus is tilted on its sides. Scientists explained that it underwent some titanic collisions in the past. This fact makes it a unique planet. 

  • Powerful Winds of Venus

Venus has a mysterious atmosphere above the surface. The Europe Venus Express mentioned that the upper winds of Venus flow fifty times faster than its rotation. 

  • Number of Solar Systems in Galaxy

Scientists estimate that there are a hundred billion solar systems in Milky Way galaxy alone. From the last 17 years, over 4,000 planets found orbiting stars. 

  • Earth Has Rare Elements

The Earth has elemental compositions like silicon, sodium, sulfur, nickel, calcium, iron, and so on. These are present in very little quantity in the whole solar system. 

  • Saturn Can Float on Water

Saturn has a very low density that it can float on water. Its average density is 0.69 grams per cubic centimeter. Since mostly helium and hydrogen together compose Saturn.
