Universe means unimaginably vast space which is unbounded with its dots of body's are by definition, the universe includes everything that abounds in space, and space is filled with matter which varies from the tiniest and cosmic particle to the gigantic galaxies. The universe is known to composed of many types of comparatively small and large dense Bo e.g., the galaxies, the constellations (star groups), the stars, the planets other heavenly bodies.
The totality of the heavenly bodies from grand galaxies down to the sm cosmic dust filling the endless space describes the Universe w dimension is beyond our comprehension.

There are t divergent theories on the mode of origin of the universe. These are the B Bang and the Steady State theories. According to 'Big Bang' theory universe has a finite beginning, through a tremendous explosive expansion superdense and very condensed matter. The "steady state" theory states the universe expands through a process of continuous creation of matt which (the process) remains unchanged through eternity.There are 8 types of planet in universe . Firstly is Mercury which is the nearest sun . Second is Venus . Characteristics of Venus is the second planet from the Sun, and considered in many ways to be a twin planet of Earth. It has a similar size, mass, density and gravity, as well as a very similar chemical composition . Next is Earth. Our planet (Earth) is a rotating sphere that orbits the Sun. The Earth's axis of rotation is at a constant tilt with respect to its orbit around the Sun, resulting in the change of seasons. The physical characteristics of the Earth include its size and composition. The Earth also has gravity and magnetic force fields.Earth where living thing live. Futhermore , Mars . Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the volcanoes, valleys, deserts, and polar ice caps of Earth.Nevertheless , Jupiter which is place on center where all the planet stand.Jupiter is composed primarily of gaseous and liquid matter. It is the largest of the four giant planets in the Solar System and hence its largest planet. It has adiameter of 142,984 km (88,846 mi) at its equator.Saturn is third last planet . Its have a ring between the glob . Saturn is the sixth planet from the sun and the second largest planet in the solar system. Saturn was the Roman name for Cronus, the lord of the Titans in Greek mythology. Saturn is the root of the English word "Saturday."
Saturn is the farthest planet from Earth visible to the naked human eye, but it is through a telescope that the planet's most outstanding features can be seen: Saturn's rings. Although the other gas giants in the solar system — Jupiter, Uranus and Neptune — also have rings, those of Saturn are without a doubt the most extraordinary.

Uranus , the planet is often dubbed an ice giant, since 80 percent or more of its mass is made up of a fluid mix of water, methane, and ammonia ices. Unlike the other planets of the solar system, Uranus is tilted so far that it essentially orbits the sun on its side, with the axis of its spin nearly pointing at the star.Last planet is Neptune . Neptune , despite being smaller than Uranus, Neptune has a greater mass. Below its heavy atmosphere, Uranus is made of layers of hydrogen, helium, and methane gases. They enclose a layer of water, ammonia and methane ice. The inner core of the planet is made of rock.
What is meteor ? The word meteor comes from the Greek word meteoron, which means "a thing in the sky." . Larger meteors are sometimes broken off pieces from an asteroid and according to ancient times, objects flying through the night sky are a major controversy.
When meteors fly through the atmosphere, they become heated up to more than 3000 degrees Fahrenheit in that causes them to glow (Space.com). While many have the impression that friction causes heat, they are incorrect in the fact that heat is produced when air is compressed in front of the meteor. Sometimes the intense heat vaporizes the meteors creating a shooting star.
Composition, speed, and the angle of entry are three characteristics that decide whether the meteor will break or hold together. A meteor coming at an intense speed and an oblique angle suffers tremendous stress (amsmeteors.com). A meteor made of iron (91% iron, 8.5% Nickel and 0.6 Cobalt) can hold its shape easier than one created by stone (36% Oxygen, 26% Iron, 18%Silicon, 14%Magnesium, 1.5% Aluminum, 1.4 Nickel and 1.3% Calcium). Iron would eventually crumble due to the atmosphere becoming less dense five to seven miles above the ground.
