Planet Detective

 In our Science, we all were learning about the different mass between one planet and another.But furthermore it was more actually based on the planet Mercury, and Earth some were questions is some how kinda not easy to answer which took me a lot of time to do. Same rule, we just need to research it and write it as an explanation writing. So my goal was to write at least 6-7 sentences, and make sure it was explained properly and it was understandable. 

What are two reasons Mercury lost most of its atmosphere?

There are many reasons why Mercury lost most of its atmosphere, unlike the other planet. It was because of the little gas it has its trillion thinner air, and at the surface of the Earth therefore it was completely undetectable by any of the normal means, and because of its lower surface of gravity even to the Sun. And any of the gases that currently exist to the surface will immediately escape within the short period of time. Did you know that Mercury’s original atmosphere formed 4.6 billion years ago with the rest of the other solar planets. It has a lower gravity because it is really close to the sun surface, and it sometimes receives some buffeting from it’s solar wind. Mercury is made out of hydrogen, helium, oxygen, sodium, potassium and water vapour. Helping this solar planet to hold on to its atmosphere is its magnetic field, while the other gravity helps the other gases to the surface. Even more the magnetic field helps to deflect the solar wind around the planet. Like it does to the Earth, the atmosphere of Mercury is also one of the most tenuous in the solar system. And that’s why the solar wind will still blow much of its way. So the sources on the planet were constantly filling up again.

Compare how close Mercury & the Earth are to the Sun

The Mercury is the closest planet in the sun, as such it circles more faster than the other planets. On the other hand the Earth is on average astronomical apart from the sun, and then Venus will be leading second after Mercury. In terms of orbits Mercury and Earth could not be more than different from one another, the hot planet(Mercury) has the most eccentric orbit other than any planet of the solar system. Just because of that it makes it closer to the sun between 46 million km, as its closest to 70 million km, as its fathers. That puts Mercury much more closer to the sun, and it will actually only take 87.969 Earth days, but for Earth it will take 365.25 days. Also Mercury will be the second descent planet after the Earth that had a huge metallic core, and even Mercury speeds around the sun every 88 Earth days. 

Compare how much mass Mercury & Earth have.

According to density, mass, and even volume. The mass and volume of Mercury is the only about 0.055 times of the Earth,but because mercury is the smallest planet among the rest it also means it has small mass that enclosed the inside a tiny body. The planet only weight in 5.427 grams per cubic centimetre, or 89 percent of the density of our planet. Approximately the Mercury mass 0.330 x 1024 kg. So we all know that Earth is also one  of the terrestrial planet, and it is the largest and densest, withe the average of 6.371.0 km. And a mean of density of 5.514 g/cm3. Furthermore the mass of the Earth will be 5.97 x 1024 kg. 

How does not having an atmosphere affect the temperature on Mercury?

We all know that the Mercury is the closet to the sun, and it doesn't have any atmosphere. And the only problem is that it intensely affects the temperature on its surface, when it doesn't have any atmosphere is present the sun during the day it enter directly leading to the very very high temperature. Just when the night and the sun is not present, the temperature of the plane is the opposite of hot. When it was cold it will make it an unfavourable to live on, as it does't have any atmosphere at all. The sunlight cannot be entrapped and even the temperature reaches to its minus during nights. That's one of the reason why we were lucky enough to live in Earth, because it was not that really close to the sun unlike the Mercury and the other planet who was affected by this.

Where do names Mercury and Whiro come from? What are some other names of the planet?

Mercury or also called Takero, Aparangi, or Whiro. Whiro actually stands for the lord of darkness and embodiment of all evil , in Maori mythology. He inhabits the underground and it was responsible for the ills of all the individuals, as a contrast to his brother and to his enemy Tane. For Neptune it was called Tangaroa or Takaroa, for Uranus it was known in Maori as Rakipo, Wherangi or Rangipo. For the Earth, this has a personal name Papatuanuku. Then for the moon it was usually called as Marama but sometimes it was called as Rona, Mars as Matawhero sometimes Tumataueka. Jupiter can be called as Parearau, Kopunui or Rangawhenua. Then lastly Saturn it was called Parearau, it was confusing because it has the sme dilect as the Jupiter.But it was most commonly called Rongo.
