What is Exoplanet | How Exoplanet formed | Where is Exoplanet | full information | spacexstn |

 An Exoplanet is also known as extra-solar planet. The Exoplanet is a planet outside the solar system. The first possible evidence of an Exoplanet was noted in the year 1917, but it was not recognized as such. The first confirmation of detection was in the 1992. This was followed by the confirmation of a different planet, which was fundamentally discovered in the year 1998.

WHAT IS AN EXOPLANET AND HOW ARE THEY FOUND

The Planet orbiting other stars are known to be as Exoplanet. All the Planets in our solar system revolve around the Sun. ... Therefore, astronomers use other methods to identify or detect and study these distant Planets. They search for Exoplanet by impact of these Planets on those Stars.

WHO DISCOVERED THE EXOPLANET

In the year 1992, on 9th of the January, the radio astronomer Aleksander Wolszczan and Dale Frail announced the discovery of the two planet which are revolving the pulsar PSR 1257+12. This was clearly confirmed. and it is generally known to be the first definitive detection of exoplanets.

WHAT ARE EXOPLANET MADE OF

The astronomer generally believe that rocky exoplanets are composed - just as Earth is - by the mass of carbon silicon, oxygen and magnesium, only a small fraction of carbon. In contrast, carbon - rich planets can contain between a small percentage and three quarters of their mass in carbon.

HOW DO EXOPLANET FORMED

The Gravitational instability is the '' top down '' method: The exoplanets are formed directly from the large structures of young stars orbiting dust and gas. ... Even if rocks are formed, they still flow very rapidly into the Stars, which are fast enough to leave their millennia in the large objects.

HOW MANY EXOPLANETS HAVE BEEN FOUND

Till now, more than 4,000 exoplanet have been discovered and declare to be be confirmed exoplanets. However, there are thousands of other '' candidate '' exoplanet detectors that require further observations to say whether the observer is genuine or not.

CAN WE SEE EXOPLANET

May be, but i am not sure, Unlike the planets that can be seen is our solar system, most of the exoplanets have not been directly used. ... One of the popular ways to see and identify the exoplanet, is to watch for a dip in the glow of the Star as the planet passes in front of it. Most of the exoplanet have been detected using this technique.

HOW EXOPLANET GET ITS NAME

To orbit a single star, it is usually named after its parent Star and by adding lowercase letters. A provisional or temporary IAU - sanctioned standard exists to accommodate the naming of the planets orbiting two stars, which are known to be as circumbinary planet.

TEMPERATURE OF EXOPLANETS

The Hubble observation exoplanet is called WASP-43b, which has no place to call home. This is a world of extremes, where strong wind speed of 3,000 degrees Fahrenheit '' day '', warm enough to melt steel, down to 1,000 degrees Fahrenheit from pitch to black '' night ''. Falls. .

FACTS ABOUT EXOPLANETS

1 : Known exoplanets come with a range of sizes, mass, and orbital position. The size and mass are smaller and less massive than the Earth from the super Jupiter type world. The orbital position ranges from very close to that of the parent.

2 : The astronomers are beginning to find and measure the atmosphere around distant exoplanets. This helps them understand what gases are present in those gaseous envelope.

3 : Among other features, astronomers ca measure surface temperatures, orbits, magnetic fields, and colors of exoplanets. As detection methods improve, they will be able to find out more about distant worlds. 

4 : An exomoon has been found in at least one exoplanet, while leaving behind traces of another materials as it evaporates, while also orbiting its stars.

5 : The area around a Star where liquid water can exist on the surface of a solid planet is called a habitable zone. Circumcision of worlds is considered the prime candidate in an area where life can be supported.

6 : More than 22 percent of Sun like Star are Earth sized planets in their habitable zones. These are important places to focus exploration of a potentially life beariing world.
