Beyond Earth: Fun Facts about the Solar System

Approximately 4.6 billion years ago, the solar system was formed – it all began with the gravitational collapse of a giant molecular cloud with its sun was formed from the collected mass and the dust creating a flat disk around it. However, the solar system is much cooler than that!

Here are the top fun facts about the solar system that you probably didn’t know, even if you try this solar system quiz, which is very interesting.

#1: Mercury isn’t the hottest planet

It is no brainer that the Mercury is the closest to the sun; however, in spite of everyone’s assumption, the Mercury isn’t the hottest planet in the solar system but it’s Venus. Venus – the second planet from the sun has a maintaining temperature of 462 degrees Celsius – is hotter than the Mercury; this is because the Mercury wasn’t formed with any atmosphere. It is the atmosphere that can trap and hold the heat.

#2: The Sun is a large star

While the sun is the heart of the solar system and plays a huge part in gravitational pull, the big hot and glowing ball is also a star, which is also known as, “the Yellow Dwarf”.

#3: It takes 8 minutes for the sunlight to reach the earth

The earth is located 150 million kilometers away for the sun with its traveling distance is approximately 186,282 miles per second speed of light. Thus, with the distance between the sun and the earth, it will take the sunlight to reach the earth at 8 minutes and 20 seconds.

#4: The closer the planet to the Sun, the faster the former orbits around the latter

According to the experts, planets that are closer to the sun quickly orbit around it; for instance, the planet Mercury can finish an orbital trek at 88 days, while the earth takes 365.256 days. The planet Neptune has the longest orbital period with 60,182 Earth days, which is equivalent 164.8 years.

#5: Proxima Centauri is the nearest star to earth

If you love to hear more about the stars, here is a fact that you’ll love to learn, the nearest star to the Earth is known as the Proxima Centauri, also known as, “the red dwarf star”. It is approximately 4.24 light-years away from the Earth. The second start nearest to the earth is the Barnard’s Star, followed by the Sirius (the brightest star during nighttime).

#6: Milky Way Galaxy is composed of 100 billion Solar Systems

Before the discovery of other solar systems, it is believed that the solar system where the Earth is in is the only solar system present. Years after years of exploration, it is found out that the Milky Way galaxy is composed of 100 billion solar systems with different planets orbiting around other distant stars.

There are a lot of fun facts to learn about the Earth and beyond it. If you are confident enough about your knowledge about the earth, sun, stars, planets, and the Milky Way, you should try to take interesting quizzes.
