On the planet of VUV there are two sorts of creatures, Zios and Zepts. The Zios have 3 legs and the Zepts have 7 legs. The great planetary explorer Nico, who first discovered the planet saw a crowd of Zios and Zepts. He managed to see that there was a total of 15 creatures before they saw him and all rolled onto their backs and put their legs in the air. He counted 57 legs. How many Zios and how many Zepts were there? *​

Answers

Only 3 of the 9 planets in our solar system have official "discoverers" and "times of discovery". The reason is simple - all of the other planets are easily seen by the unaided human eye. This means that humankind has been looking at these objects (whether they understood what they were or not) since first gazing at the night sky!

Three planets required good telescopes for their discovery:

Sir William Herschel
Uranus was discovered by Sir William Herschel in 1781. Herschel was probably the most famous astronomer of the 18th century. In addition to discovering the planet Uranus, he also observed and cataloged over 800 double stars and 2,500 nebulae. He was the first astronomer to correctly describe the spiral structure of our Milky Way Galaxy.

John Couch Adams
Neptune was discovered by John Couch Adams in 1846. Adams was an English astronomer and mathematician who, at the age of 24, was the first person to predict the position of a planetary mass beyond Uranus. Adams did not publish his prediction and it is a miracle that he is given credit by the scientific community for his work (let this be a lesson!). German astronomer Johann Gottfried Galle (along with Heinrich Louis d'Arrest) confirmed the existance of Neptune based on independent, published, calculations done by French mathematician Urbain Jean Joseph Le Verrier. Sometimes you will see Couch and Le Verrier cited together as the "discoverers of Neptune".

Clyde Tombaugh
Pluto was discovered by astronomer Clyde Tombaugh in 1930. A 9th planet had been looked for for some time. It was believed that such a planet had to exist in order to explain some odd things happening in the orbits of Uranus and Neptune. Tombaugh did a careful sky survey at the Lowell Observatory in Arizona. As a result, he discovered Pluto. The interesting thing to know is that all of the orbital problems with Uranus and Neptune vanish when the correct mass of Neptune is used in the equations; the correct mass was determined by the Voyager 2 spacecraft when it flew by that planet in 1989. So Tombaugh got lucky - he found a planet where a flawed prediction said one would be!

answer:

exoplanets

Explanation:

To date, more than 4,000 exoplanets have been discovered and are considered "confirmed." However, there are thousands of other "candidate" exoplanet detections that require further observations in order to say for sure whether or not the exoplanet is real.
