Milky Way Galaxy is the Spiral type of galaxy. Stars have the light of their own.

Solar system , assemblage consisting of the Sun —an average star in the Milky Way Galaxy —and those bodies orbiting around it: 8 formerly 9 planets with about known planetary satellites moons ; countless asteroid s, some with their own satellites; comet s and other icy bodies; and vast reaches of highly tenuous gas and dust known as the interplanetary medium.

Solar System and Universe

Milky Way Galaxy is the Spiral type of galaxy. Stars have the light of their own. They are made up of vast clouds of gases like Helium, Hydrogen, etc. Protostar is a highly condensed cloud of gases like Hydrogen and Helium.

A Black Hole is a region of space with a very strong gravitational field that even light cannot escape from its surface. The second nearest star to the Earth is Alpha Centauri. The photosphere is the glowing surface of the Sun. The chromosphere is the layer above the photosphere. The Corona is the outer atmosphere of the Sun. The outwards emission of large, bright, gaseous features from Sun is known as Prominence.

The temperature of the core of the Sun is about 15 million degrees Celcius. The circumference of the moon is about km. The average distance from the Earth to the Moon is about , km. In one revolution of Earth, the moon takes 27 days , 7 hours, and 43 minutes. The reflected light of the Sun from the Moon reaches the Earth in 1.

Neil Armstrong landed on the moon on 21 July There is no atmosphere on the moon. Earth takes almost days and 6 hours to complete an orbit of the Sun. Earth is also called the Blue Planet. Perihelion is the nearest position of the Earth in the orbit of the Sun- 3 January. Aphelion is the farthest position of the Earth in the orbit of the Sun- 4 July.

The nearest planet to the Earth is Venus. The Earth revolves around the Sun at a speed of The Earth completes a revolution along its axis in around 24 hours 23 hours, 56 minutes, and 4 seconds. Tides are the rise and fall of levels of sea levels.

Venus has the same period of rotation and revolution. Earth and Mars have almost the same rotation time along their axis. Mars rotation time along its axis is 24 hours, 39 minutes, and 35 seconds. Earth rotates eastward around its axis. Jupiter is the biggest planet. Venus is the brightest planet. Mars is also known as the Red Planet. Venus rotates from East to West.

Venus is also known as the Morning and Evening star. Uranus rotates from North to South. Saturn and Uranus are known as the planets with ring. Planet revolves around the Sun in an Anti-clockwis e direction. Venus is the nearest planet of the Earth. Venus is the hottest planet. Important Facts: There are 8 planets in our solar system. Planets are revolving around Sun in elliptical orbits.

Sun rays take approx 8 minutes 16 seconds to reach the Earth. The name of our galaxy is Milky Way. Pluto is a dwarf planet. The nearest planet to the Sun is Mercury. Farthest planet to the Sun is Neptune. The smallest planet among all the eight planets in our solar system is Mercury. The largest planet among all the eight planets in our solar system is Jupiter. Saturn is the second-largest planet in our solar system. Uranus is the third-largest planet in our solar system.

Major gases that the sun contains are Hydrogen and Helium. Mercury: The closest planet to the Sun. Orbits the Sun quickest. No significant Atmosphere. No natural satellites. Venus: Hottest planet. Longest rotation period. The dense atmosphere of gases. Revolves around the Sun from East to West.

Only Venus and Uranus rotate from East to West. No natural satellite. Earth takes approx 24 hours to rotate on its own axis. You may also like.

But the processes by which planets, stars, galaxies, and the universe form and change over time are also types of "evolution. In the late s the American astronomer Edwin Hubble made a very interesting and important discovery. Hubble made observations that he interpreted as showing that distant stars and galaxies are receding from Earth in every direction. Moreover, the velocities of recession increase in proportion with distance, a discovery that has been confirmed by numerous and repeated measurements since Hubble's time.

The Solar System [b] is the gravitationally bound system of the Sun and the objects that orbit it, either directly or indirectly. Of the objects that orbit the Sun indirectly—the natural satellites —two are larger than the smallest planet, Mercury. The Solar System formed 4. The vast majority of the system's mass is in the Sun, with the majority of the remaining mass contained in Jupiter. The four smaller inner planets, Mercury, Venus , Earth and Mars , are terrestrial planets , being primarily composed of rock and metal.

The universe is filled with billions of star systems. Located inside galaxies, these cosmic arrangements are made up of at least one star and all the objects that travel around it, including planets, dwarf planets, moons, asteroids, comets, and meteoroids. Astronomers believe it formed about 4. Along with the sun, our cosmic neighborhood includes the eight major planets. The closest to the sun is Mercury , followed by Venus , Earth, and Mars.

The Solar System includes the Sun, the Earth where you are now! The biggest planet is Jupiter — you could fit 1, Earths inside Jupiter. The Sun is even bigger than Jupiter — it would take 1. It takes just over days for the Earth to travel all the way around the Sun. We call the length of time it takes to go around the Sun a year, but to make life easier, most years have days and every 4th year has days. We call a year with days a leap year. The extra day is February 29th.
