Task 6 - A Planet of the Solar System

-

 The solar system


 The Solar System is located in the Milky Way, a barred spiral galaxy with a diameter of about 100,000 light-years containing more than 100 billion stars The Sun resides in one of the Milky Way's outer spiral arms, known as the Orion-Cygnus Arm or Local Spur.

The Solar System is the system where all planets are attached to each other, other moons and the Sun, all bound by gravity, either directly or indirectly. 

It consists of a star; the Sun, the planets; a total of nine, dwarf planets; such as Pluto, moons and millions of asteroids, comets and meteoroids. The Solar System also contains smaller objects. The asteroid belt, which lies between the orbits of Mars and Jupiter, mostly contains objects composed, like the terrestrial planets, of rock and metal. Beyond Neptune's orbit lie the Kuiper belt and scattered disc, and beyond them a newly discovered population of sednoids.








                        





  Mercury



General information:


This small planet spins around slowly compared to Earth, Mercury takes 59 Earth days to make one full rotation. 

Along with Venus, Earth, and Mars, Mercury is one of the rocky planets. It has a solid surface that is covered with craters. 

It orbits the Sun every 88 days. 

It is named after the Roman god Mercurius.

Physical Characteristics:


Mercury appears to have a solid silicate crust and mantle overlying a solid, iron sulfide outer core layer, a deeper liquid core layer, and a solid inner core.

The planet's density is the second highest in the Solar System.

Mercury’s  diameter  is 4880 km.


Surface geology:


Mercury's surface is similar in appearance to that of the Moon, indicating that it has been geologically inactive for billions of years. 

The planet's mantle is chemically heterogeneous, suggesting the planet went through a magma ocean phase early in its history. 


Habitability:

There may be scientific support, based on studies reported in March 2020, for considering that parts of the planet Mercury may have been habitable, and perhaps that life forms, albeit likely primitive microorganisms, may have existed on the planet.

Comparasion:

Here is Mercury compared to other planets.

  · Big Bang The Universe we know nowadays began in a Big Bang about 14 billion years ago. The entire Universe was inside a bubble thousands of times smaller than a pinhead. Then, it suddenly exploded. The Universe was born. Time, space and was created. In less than a second, the Universe grew to a whole galaxy.  As the Universe expanded and grew it cooled and particles changed to matter and antimatter. These two types of particles destroyed each other, although some matter survived. More particles like neutrons, protons and atoms started to form when the Universe was one second old. Within the first seconds, the entire Universe’s temperature dropped 1 billion degrees Celsius and it was cold enough for the protons and neutrons to come together, forming hydrogen and helium nuclei. After 300 000 years, the Universe had cooled to about 3000 degrees.

Task 7-The constellations

                  The constellations A constellation is a set of fixed stars or unrelated stars that form an imaginary pattern.There are 88 constellations.The Greeks discovered the constellations. To find a constellation you have to be in a place with no light and no full moon,  knowing the constellations can be of great help to quickly orient yourself. Aries   Leo Ursa Major Eridanus Ursa Major’s history : Ursa Major (also known as the Great Bear) is a constellation in the northern sky, whose associated mythology likely dates back into prehistory. Its Latin name means "greater (or larger) she-bear," referring to and contrasting it with nearby Ursa Minor, the lesser bear. In antiquity, it was one of the original 48 constellations listed by Ptolemy in the 2nd century AD. Today it is the third largest of the 88 modern constellations. Ursa Major is visible throughout the year from most of the nor...
