On February 18, 1930, he compared photos of a single star field – taken six days apart a few weeks earlier – and noticed an object that was moving against the backdrop of distant stars. New Horizons images of a region near Pluto’s equator revealed a range of young mountains rising as high as 11,000 feet (3,500 meters) above the surface of the icy body. The process was laborious: Tombaugh would photograph the same part of sky several days apart and use a Zeiss Blink Comparator to detect the motion of a nearby planet against the more distant “fixed” stars. 5 6 7.

The name denotes both the assumed unfavorable surface conditions (as Pluto was the Roman god of the underworld) and also honors Percival Lowell, as Lowell's initials make up the first two letters of the planet's name.
Looking through his homemade telescopes, Tombaugh made drawings of Jupiter and Mars which so impressed the people at Lowell Observatory at Flagstaff, Arizona they offered him a job in 1929 where he was employed until 1945. Tombaugh was fortunate to find Pluto after only searching for a few months. This great distance from the sun makes Pluto very inhospitable; it's surface is expected to be made up of mostly ice and rock and it takes Pluto 248 years just to make one orbit around the sun.

Lowell had noticed that the gravitational pull of something large was affecting the orbits of those two planets.
Very soon after Pluto’s discovery, astronomers realized it was too tiny to cause the supposed irregularities in Uranus’ orbit. Clyde Tombaugh carefully studied images of the night sky, and after a lot of hard work he finally discovered Pluto. He’d dreamed of becoming an astronomer, but gave up the possibility of attending college after his family’s crops were destroyed by a hailstorm. Choose the plan that’s right for you.
Once Tombaugh got going toward the end of 1929, the discovery came remarkably rapidly: on February 18, 1930, he found the distant planet on plates taken on the 23rd and 29th of January. The location of an eighth planet was mathematically predicted. In 1980, the International Space Hall of Fame inducted him. Comparing thousands of images, Tombaugh discovered Pluto.
He also discovered a number of asteroids and minor planets, and he was one of the supporters of further research to better understand UFOs or unidentified flying objects.
Thirteen years later, the Lowell Observatory (founded in 1894 by Percival Lowell) decided to recommence Lowell's search for Planet X. Tombaugh also found a number of asteroids.

On behalf of the Observatory, he presented the Lowell Prize to the top mathematics student at Arizona State Teacher’s College at Flagstaff (today known as Northern Arizona University). Ultimately, he worked as an observer for Lowell Observatory from 1929 until 1945. At the time of its discovery, Pluto was considered to be the ninth planet in the solar system. Like the rest of Pluto, this region would presumably have been pummeled by space debris for billions of years and would have once been heavily cratered — unless recent activity had given the region a facelift, erasing those pockmarks. For over seven decades, Pluto was considered the ninth planet of our solar system.
He also discovered several clusters of stars and galaxies, studied the apparent distribution of extragalactic nebulae, and made
This heart-shaped region is a vast plain on the planet covered with nitrogen ice. Bottom line: Clyde Tombaugh discovered Pluto on February 18, 1930, at the Lowell Observatory near Flagstaff, Arizona.
Plus, Pluto's moon (Charon, named after Charon of the underworld, discovered in 1978) is incredibly large in comparison.

Later, to the chagrin of many astronomers, it was demoted by the International Astronomical Union in 2006.
The new telescope was completed in 1929, and the Observatory hired a farm boy from Kansas named Clyde Tombaugh, who had impressed director V. M. Slipher with some unsolicited sketches, to renew the search.
The existence of a planet beyond Neptune had been predicted by prominent American astronomer, Percival Lowell in 1905 but it was never proven in his lifetime. During the 1950's he worked at the White Sands Missile Range, New Mexico and taught astronomy at New Mexico State University, where he stayed until his retirement in 1973.
The name denotes both the assumed unfavorable surface conditions (as Pluto was the Roman god of the underworld) and also honors Percival Lowell, as Lowell's initials make up the first two letters of the planet's name.
Looking through his homemade telescopes, Tombaugh made drawings of Jupiter and Mars which so impressed the people at Lowell Observatory at Flagstaff, Arizona they offered him a job in 1929 where he was employed until 1945. Tombaugh was fortunate to find Pluto after only searching for a few months. This great distance from the sun makes Pluto very inhospitable; it's surface is expected to be made up of mostly ice and rock and it takes Pluto 248 years just to make one orbit around the sun. On February 18, 1930, Tombaugh discovered the tiny, distant planet by use of a new astronomic technique of photographic plates combined with a blink microscope. He’d been hired to continue a search for a ninth planet, begun by Percival Lowell.
They had observed wobble in the outer planets' orbits, and hypothesized that it was caused by some as-yet-unknown planet in a trans-Neptunian orbit.
Yet the mystery wasn’t solved. It was a small, dim, remote body in our own solar system. In 2006, the International Astronomical Union changed the status of Pluto from one of nine major planets in our solar system to a dwarf planet.
The ...read more. All that time, the mystery of Pluto continued. Not long afterwards, in 1846, astronomers searching with telescopes found Neptune – the 8th planet – based on those predictions. Lowell had gained fame for his notion of canals on the planet Mars. He found it using a "blink comparator," a device with which you flip between two images—each taken by the astrograph—and spot tiny dots that move in an unexpected way.
They couldn't all be considered full-fledged planets. The discovery occurred on February 18, 1930 while Tombaugh was carefully examining a set of photographic plates created by the telescope. The mystery of Pluto began long before Clyde Tombaugh’s momentous discovery. Unfortunately, few, if any, of the audience members heard this important message, since the soft-spoken Lampland could not be heard in the echo-filled, uncarpeted room. When Clyde Tombaugh discovered Pluto in February 1930, I was in high school at Westport High in Kansas City, Missouri. Astronomers in the 19th century knew the seventh planet Uranus as outermost planet in our solar system. For many years, Pluto was considered to be the ninth planet in our solar system. I graduated in 1931, and about a year later my widowed mother moved us to Lawrence, Kansas. Image via Lowell Observatory.
ADDRESS Beginning in the 1990's astronomers questioned Pluto's status as a planet.

Lowell had noticed that the gravitational pull of something large was affecting the orbits of those two planets.
Very soon after Pluto’s discovery, astronomers realized it was too tiny to cause the supposed irregularities in Uranus’ orbit. Clyde Tombaugh carefully studied images of the night sky, and after a lot of hard work he finally discovered Pluto. He’d dreamed of becoming an astronomer, but gave up the possibility of attending college after his family’s crops were destroyed by a hailstorm. Choose the plan that’s right for you.
Once Tombaugh got going toward the end of 1929, the discovery came remarkably rapidly: on February 18, 1930, he found the distant planet on plates taken on the 23rd and 29th of January. The location of an eighth planet was mathematically predicted. In 1980, the International Space Hall of Fame inducted him. Comparing thousands of images, Tombaugh discovered Pluto.
He also discovered a number of asteroids and minor planets, and he was one of the supporters of further research to better understand UFOs or unidentified flying objects.
Thirteen years later, the Lowell Observatory (founded in 1894 by Percival Lowell) decided to recommence Lowell's search for Planet X. Tombaugh also found a number of asteroids.
