The solar system fascinates us with the distinct structures and characteristics of its members. The solar system is just like a big family. It has many members namely; sun, planets, asteroids, comets,meteorites and moon s that move around each planet.

| Sun |
The sun is the center of the solar system. It gives off heat and light that reach each planet. The heat it produces has brought both significant and insignificant to any form of creation.The sun is a big ball of gases. These gases give the sun its brightness and hotness. The sun is one of our medium-sized stars and is about 1 380 000 kilometers across. It is surrounded by eight planets.

| Mercury |
These planets are divided into two classifications -the smaller inner and outer planets. The smaller inner planets are composed of Mercury, Venus, Earth and Mars that is also called terrestrial planet.While outer planets include Jupiter, Saturn, Uranus and Neptune.These are gas giants and are substantially more massive than the terrestrial. Mercury is the nearest planet to the sun. Mercury possesses a thin exosphere made up of atoms blasted off its surface by solar wind and striking micro meteoroids. Because of the planet's extreme surface temperature, the atoms quickly escape into space.There has been no wind erosion of the surface and meteorites do not burn up due to friction as they do in other planetary atmospheres.

| Venus |
Venus is oftentimes called as "Earth' sister". It is covered with an opaque layer of highly reflective clouds or sulfuric acids, preventing its surface from being seen from space invisible light. Venus has the densest atmosphere of all the terrestrial planets in the solar system, consisting mostly of carbon dioxide.

| Mars |
 |
| The Earth |
Earth is the only planet that provides life.It rotates as it revolves around the sun and never stops. Its rotation causes day and night. It rotates on its own axis for 24 hours and revolves365 1/4 days around the sun. Mars has approximately half the radius of Earth. It is less dense than Earth, having about 15% of Earth's volume and 11% of the mass. The rotation and seasonal cycles of Mars are likewise similar to those of Earth, as is the tilt that produces the seasons. Moreover, the Olympus Mons- the highest known mountain within the Solar System and also the largest canyon, Valles Marineris are seen on Mars.

| Uranus |
 |
| Jupiter |
In addition to, Jupiter and Saturn are composed of hydrogen and helium. Jupiter is the largest planet. It has a rocky core composing heavier elements. Jupiter is as like as earth's shape- oblate spheroid that is caused by its rapid rotation. Saturn is the sixth planet from the sun and the second largest planet in the solar system. While Uranus and Neptune are made up of ices such as water, ammonia, and methane. They are classified as "ice giants". These are ringed planets because they are encircled by planetary rings of dust and other particles.

| Neptune |
 |
| Moon |
Long times, Pluto was considered as planet but was re- categorized because it changes its axis and was discovered as one of the dwarf planets. Each of these planets are orbited by moons. These are called as "natural satellites". These are not as hot as as the sun. Astronomers have found out that moons have rocks, mountains and deep holes (crater). It is one of the sources of light at night. Aside from the planets around the there are still other heavenly bodies that are part of the solar system. These are the comets, meteors and asteroids. Comet has head and tail that shines brightly while asteroids are myriad of stars lie between two planets. They also move around the sun. Lastly, meteorites are shooting stars that fall. Meteorites can form landforms when they hit a certain planet. These things are somehow develop our curiosity to intervene with their personal look and on how they are appeared in the outer space given that they are unfamiliar to our sense of sight except for the pictures that astronomers have provided to us.
