What is a Planet?

A planet is a heavenly body that moves in an orbit around a Star, such as sun. In other words, we can say that some heavenly bodies that don’t have their own heat and light. Such bodies are called Planets.

The word Planet comes from the Greek word “Planetai” which means ‘Wonders‘.

There are 8 planets in our Solar System. All the eight planets move around  the Sun in a fixed path. The Sun is situated in the center. The sun provides light and heat to all the eight planets and to their satellite.

Transit of Venus

A transit of Venus occurs when Venus passes directly between the Sun and Earth. This alignment is rare, coming in pairs that are eight years apart but separated by over a century.

The last thrilling sight was in 2004 and this is 2nd transit which is last of 21st Century. The next transit will be in the year 2117. One of the most spectacular celestial phenomenon transit of Venus is being observed over a large stretch of Asia including India, Philippines, Australia, North America.


  • Earth is the third planet to the Sun.
  • Earth is one of the only planets that contain life.
  • The Revolution Period of the earth is 365 days, 5 hours 48 minutes 46 seconds.
  • Period of rotation is 23 hours 56 minutes, 4 seconds.
  • It has only one satellite i.e moon.
  • It is only a suitable place for living.


  • Mars is the fourth nearest planet to the Sun.
  • Mars is called Red Planet because it appears as a reddish ball when looked through a telescope.
  • Revolution Period 687 days.
  • Rotation Period 24.6 hrs (almost equal to Earth)
  • It has two satellites, Phobos and Deimos.
  • It has signs of water.
  • There is the possibility of life.
  • It has a thin atmosphere comprising Nitrogen and Argon.
  • Beneath its atmosphere, Mars is barren, covered with red oxide mixed soil and boulder. Because of this, it is known as ‘Red Planet‘.
  • Various space missions have been sent e.g. Pathfinder, Mars Odyssey.


  • It is the largest of all planets in the solar system and almost 11 times on Earth.

Why Pluto is Considered as Dwarf Planet?

The Pluto was discovered in 1930 by Clyde Tombaugh. It was considered as the 9th and smallest Planet in the Solar System.

Since 2006 the IAU (International Astronomical Union) removed it from the list of Planet. Because of Pluto orbit beyond the orbit of Neptune. It is much smaller than any of the official Planets and now classified as a Dwarf Planet.

It is the second-largest Dwarf Planet in the Solar System.

  • The Comet is a member of the Sun’s family, part of the Solar system.
  • Comet travels in an elliptical orbit around. the Sun regular schedule.
  • It has a head and a tail. Its tail originates once it gets closer to the Sun.
  • May have originated from a huge cloud the ‘Oort cloud’ that is thought to surround the Solar system.
  • The brightest part of the comet is head (coma).
  • It is made up of solid matter combined with gases.


  • Asteroids or minor planets circle in a broad belt between the orbits of Mars and Jupiter.
  • It is the debris leftover from the formation of inner planets. Also called ‘Planetoids’ or small planets.
  • They are chunks of rock covered in frozen gases.


Meteoroids are small bodies that travel through space. Meteoroids are smaller than Asteroids, most are than the size of a pebble. Meteoroids have many sources. Most meteoroids come from asteroids that are broken apart by impacts with other asteroids. Other meteoroids come from the Moon, from comets, and from the planet Mars.

It is sometimes called a shooting Star or a falling Star. The friction between the fast-moving meteor and the gas in the Earth’s atmosphere causes intense heat, the meteor glows with heat and then burns. A meteor shower is a phenomenon in which many atmospheres in a relatively short time and in approximately parallel trajectories. A very intense meteor shower is called a meteor storm.


A Meteorite is a Meteor that has fallen to Earth. These rare objects have survived an atmosphere and have lost a lot of mass Meteorites are made up of rock and/or metals.
