Essays on Radial Velocity

The paper discusses Kepler 186 exoplanetary system. It explains the technique of detecting Kepler 186 system, the structure, as well as its layout. Exoplanetary system denotes planets orbiting around a star other than the sun, or it is beyond the solar system (Charles, 2015).

Technique for Detecting Kepler 186

The method used to detect Kepler 186 is transit technique. A planet is described as transiting when it passes between its star and the planet Earth. As the planets of Kepler 186 pass between the Earth and the Kepler 186 star, the star's light is caused to dim, and this is detected by an instrument. ...

<Institutional Affiliation> The main reason why theories are created is that they tend to explain a fact or a phenomena using suggested ideas that are based on principles. Landing to the moon is an activity that was practiced and witnessed by human beings. Therefore, no theory is needed whatsoever to explain the event. The speed to be measured is that of wind. The materials needed are: four cups whose shapes are hemispherical, and a spindle. The cups are attached to the spindle and the spindle vertically mounted on the ground, in such a way that the cups are ...

How were Uranus's rings discovered?

William Herschel was the first observer to mention that Uranus has a ring system in 1789. It was only a speculation since the astronomers that time could not observe any rings around Uranus. The discovery of the Uranian ring system was observed almost 200 years later by James Elliot, Edward, Dunham, and Douglas Mink in 1977. The discovery of the ring system of Uranus was only an accident when they grabbed the opportunity to observe the atmosphere of the planet using the occultation of the star SAO 158687. In their observations, they found out that the star suddenly disappeared for five ...
