15 Interesting facts of Mercury – explore now

Mercury is the smallest planet we all know.  But you will also agree with me that it is one of the interesting planets.

Then there is a question: what makes it interesting? 🤔 

Its size, its fast rotation or its interesting facts, I think all of them.

 So in this post, we are going to see some of the most interesting facts of mercury.

So let’s get started:

Interesting facts of Mercury

Mercury

1. There is ice present on Mercury

Mercury is nearly 3 times closer than Earth to the sun. Sun can evaporate water from the earth.

So how ice can be present in mercury? In reality, there are many places on mercury where light or heat never goes. That is why ice presents in the craters of the planet. (Source)

2. The biggest temperature change is from 452 to – 173. 🌡️

We all know why mercury is extremely hot. But It is also proved that its surface is extremely cold also.

On the day its temperature is around 840-degree Fahrenheit (451-degree Celsius) but at night it goes minus 275 Fahrenheit (-170 degrees Celsius.)

 You can see a change of temperature of about 1100 degrees Fahrenheit (600-degree Celcius).

 It’s all because of Mercury’s thin atmosphere that can not maintain the heat that it gets in the day.

3. Sun from mercury🌄

 It is not easy to match eyes with the sun. We all know the closest planet to the sun is Mercury.

So have you thought about how the view of the Sun will be from Mercury? Well, far more different than from others.

According to scientists if you are standing on mercury then the sun in the sky will look 3 times larger and its sunlight will look 7 times brighter than it is on earth.

4.Fastest rotating planet of the solar system⏩

It travels with a speed of about 1,12,000 mph (180000 kilometres per hour) in its orbit. 

This planet is just 29 million miles far from the sun. The most interesting thing is that it is not only the closest planet to the sun but also the fastest planet in the solar system.

 And that’s why it only takes nearly 88 Earth days to complete its orbit. It orbits so fast that early civilization thought it two different stars.

5. 75% of Mercury’s radius is only the iron core.

Believe it I know it is very difficult but this is true. This iron core has metal more than any other planet in the whole Solar system.

Now the question is: how it is formed?

But, no one knows how it was formed but scientists think if the planet formed quickly it could have left a thin sheet of crust over the relatively large iron core.

6. Mercury is crazily small

 Mercury is the smallest planet in our solar system we all know this. But do you know how small it is:

 Its diameter is about 3030 miles (48706 kilometres) that are slightly bigger than Earth’s moon and much smaller than the moon of Saturn’s Titan and Jupiter’s Moon Ganymede.

7. Mercury has the most no. of craters

While Mercury’s atmosphere is so weak so there is nothing to protect it against meteor impacts.

These meteors have filled their surface with craters and have given Mercury a very similar look to our Moon.

8.There is a piece of Mercury here on Earth

Here is a quick story:

In 2012, a green colour meteorite was found being sold at a street market in Morocco. 

After studying its composition, many astronomers believe it might have come from Mercury.

 As it matches all the data we have gathered about Mercury by the MESSENGER probe. This meteorite could have arrived after one of the many impacts on Mercury that sent some pieces of it flying into space.

9. The thinnest atmosphere of the solar system.

 Mercury has the thinnest atmosphere than any other planet in the solar system.

 It is because of solar winds.

 Its atmosphere is that much thin that scientists have given it another name for an atmosphere like this and that is “exosphere“.

 After it was observed that the moon and other bodies also have this kind of atmosphere then this is possibly a reason what makes it the most common atmosphere of the solar system.

10. See different names of Mercury

It can be seen with naked eyes from the earth. I think that’s why it was known much before.

 And that’s why it has many names that are given by almost every culture.

  1. Mercury is the fastest rotating we have seen above that is the reason that why Romans named it after their Swift footed messenger God.

2. The Sumerians knew about Mercury from at least 5000 years ago. It was named after it their god of writing Nabu.

3. And in Indian culture, it was known as Budha and they also have day named on this.

It was also known as The Morning Star and The Evening Star.

11. What: In Mercury’s one year there is only 1.3 day.🗓️

 This is very shocking.

 It is the fastest planet in the solar system but it rotates very slowly around its axis.

 It takes only 88 Earth’s days to revolve around the Sun but it takes 59 earth’s days to rotate around its axis.

We can also say that its day changes only once a year completely. It will be irritating if you have to wait for 59 days to go back to bed.

Venus rotates on its axis in a direction that is opposite of most solar planets. It means on Venus, the sun would appear to rise from the west.

 12. Second densest planet.

After all that it is very small but it is also the second most dense planet.

 Each cubic centimetre has a density of 5.4 grams. After, Earth has the highest density. This is all because mercury is being composed of mainly heavy metals and rocks.

 13. The biggest crater of the solar system

As we have seen that Mercury has a very weak atmosphere that’s why it has no defence system to protect it from meteorites or asteroids.

 That’s why there are many craters. Cori’s basin in Mercury is a crater created by the impact of a meteorite around 3.8 billion years ago. it is about 1,550 km (963 miles).

This is that much big that in which from Portugal to Germany about the whole of Europe can fit in it.

14. Shocking fact- Mercury is shrinking.😮

It is one of the most shocking facts… Well:

Mercury is not only shrinking from the past but this process continues.  

when the core cools down it solidifies and reduce its volume and causes it to shrink. (Source)

15. Mercury also has some wrinkles

what is your meaning by wrinkles? you are joking.

No, as the iron of the planet cooled and contracted the surface of Mercury became wrinkled.

Scientists have named these wrinkles the lobate scarps.
