Which is the first planet to be discovered ? Who dicovered it ?

Question

Please clarify my doubt

Answer 1

You need to know you are living in a planet so may be the earth was the first planet to be found and The discoverer was god , the creator of adam and eve because he must have noticed the planet and must have thought this planet has water , air and enough temperature and gravitational force may be this will be the perfect planet for people to live in and he created human beings slowly they started to multiply and found the other planets which were existing in the outer space am I not a genius to think like this ?

Answer 2

By definition, to discover an object means it has been there for a while but nobody else has noticed it before. Whether the object is a planet, a chemical element, or an island.

If it is something everybody notices , then no one individual can be credited with its discovery. If it is something someone (a human or a deity) has made, created or invented, then what happens is that others find out about it. which is not the same thing as discovering it.

Discovery implies perspicacious observation and being the first to make that observation. We all breathe air but Lavoisier discovered oxygen in the air was what made combustible materials flammable.

Having defined what we mean, the planets known since antiquity (Mercury Venus Mars Jupiter Saturn) (and the Sun and Moon) were not discovered in the sense that Columbus discovered America.

The first solar system object to be discovered was Ganymede and it was found by the keen-sighted ancient Chinese astronomer Gan De, in 364 BC, who had no telescope but remarkably good eyesight. This was nearly 2,000 years ahead of Galileo who discovered Io, Europa Ganymede and Callisto in January 1610.

The first planet to be discovered (the above are moons of Jupiter) was Uranus in 1781 by Sir William Herschel. The name was chosen by Johann Bode, director of the Berlin Observatory who worked out its orbit.

When Ceres was discovered in 1801 it was hailed as a planet and remained classed as one for over 50 years, as were other asteroids (as we now call them) such as 2 Pallas (1802) 3 Juno (1804) and 4 Vesta (1807).

The first 20 to be found were:

1 Ceres January 1, 1801 Palermo, Sicily G. Piazzi
2 Pallas March 28, 1802 Bremen, Germany H. W. Olbers
3 Juno September 1, 1804 Lilienthal, Germany K. Harding
4 Vesta March 29, 1807 Bremen, Germany H. W. Olbers
5 Astraea December 8, 1845 Driesen (now Drezdenko, Poland) K. L. Hencke
6 Hebe July 1, 1847 Driesen (now Drezdenko, Poland) K. L. Hencke
7 Iris August 13, 1847 London, England J. R. Hind
8 Flora October 18, 1847 London, England J. R. Hind
9 Metis April 25, 1848 Markree, Ireland A. Graham
10 Hygiea April 12, 1849 Naples, Italy A. de Gasparis
11 Parthenope May 11, 1850 Naples, Italy A. de Gasparis
12 Victoria September 13, 1850 London, England J. R. Hind
13 Egeria November 2, 1850 Naples, Italy A. de Gasparis
14 Irene May 19, 1851 London, England J. R. Hind
15 Eunomia July 29, 1851 Naples, Italy A. de Gasparis
16 Psyche March 17, 1852 Naples, Italy A. de Gasparis
17 Thetis April 17, 1852 Düsseldorf, Germany R. Luther
18 Melpomene June 24, 1852 London, England J. R. Hind
19 Fortuna August 22, 1852 London, England J. R. Hind
20 Massalia September 19, 1852 Naples, Italy A. de Gasparis

Neptune was discovered in 1846 and credit is shared between Urbain Le Verrier (France), John Couch Adams (England) and Johann Galle (Germany).

Pluto in 1930 was discovered by the American astronomer Clyde Tombaugh at the Percival Lowell Observatory.

EXTRA-SOLAR PLANETS

The first to be found was orbiting a pulsar. in 1992, when Wolszczan and Frail published results in Nature indicating that pulsar planets existed around PSR B1257+12. Wolszczan had discovered the millisecond pulsar in question in 1990 at the Arecibo radio observatory. These were the first exoplanets ever verified, and they are still considered highly unusual in that they orbit a pulsar. (they are not habitable because of the intense radiation that pulsats emit).

The first to be found orbiting a Main Sequence Star was 55 Pegasi b and it was given the nickname Bellerophon. Bellerophon's discovery was announced on October 6, 1995 by Michael Mayor and Didier Queloz in Nature, volume 378, page 355, using the radial velocity method at the Observatoire de Haute-Provence with the ELODIE spectrograph.

We now know of 216 exoplanets orbiting other stars, three of which have four such planets. The latest batch in September 2006 include the puffy planet HAT-P-1b, 450 light years away and WASP-1 and WASP-2, respectively 1000 and 500 light years away.

Ther final link takes you to where all such discoveries are announced, The Extrasolar Planets Encyclopaedia, a site maintained by the Paris Observatory. not inappropriately as it was there that Urbain Le Verrier worked when Neptune was discovered.

2. Venus
3. Mercury
4. Mars
5. Jupiter & Saturn in the same year
6. Uranus
7. Neptune
8. Pluto

Answer 5

In ancient times, Grecian astronomers noted how certain lights moved across the sky in relation to the other stars. These objects were believed to orbit the Earth, which was considered to be stationary. The "wandering" lights were called "πλανήτης" (planētēs), a Greek term meaning "wanderer", and it is from this that the word "planet" was derived.

Answer 6

Five planets - Mercury, Venus, Mars, Jupiter, and Saturn were known to the ancients. To the unaided eye, these planets appear starlike. However, the planets moved relative to the stars. For this reason they were called wandering stars. Our word "planet" comes from the Greek word planetes, meaning "wanderer".
