The example above shows five catalog entries from one of the partial lists.All five asteroids were discovered at Palomar Observatory by the Palomar–Leiden survey (PLS). The MPC directly credits the survey's principal investigators, that is, the astronomers Cornelis van Houten, Ingrid van Houten-Groeneveld and Tom Gehrels. (This is the only instance where the list of minor …

The Firestone Grand Prix of Monterey is an IndyCar Series race held at WeatherTech Raceway Laguna Seca near Monterey, California.The event dates back to 1960, and became an American open wheel race in 1983. The race was part of the CART/Champ Car series from 1983 through 2004. After a fifteen-year hiatus, the event returned in 2019 as part of the IndyCar Series, …

This is a list of dinosaurs whose remains have been recovered from Africa.Africa has a rich fossil record, but it is patchy and incomplete. It is rich in Triassic and Early Jurassic dinosaurs. African dinosaurs from these time periods include Coelophysis, Dracovenator, Melanorosaurus, Massospondylus, Euskelosaurus, Heterodontosaurus, Abrictosaurus, and Lesothosaurus.

New York State Route 17 (NY 17) is a major state highway that extends for 397 miles (638.91 km) through the Southern Tier and Downstate regions of New York in the United States. It begins at the Pennsylvania state line in Mina and follows the Southern Tier Expressway east through Corning to Binghamton and the Quickway from Binghamton east to Woodbury, where it turns …

The Kuiper belt (/ ˈ k aɪ p ər /) is a circumstellar disc in the outer Solar System, extending from the orbit of Neptune at 30 astronomical units (AU) to approximately 50 AU from the Sun. It is similar to the asteroid belt, but is far larger—20 times as wide and 20–200 times as massive. Like the asteroid belt, it consists mainly of small bodies or remnants from when the Solar System …

In 2011, the director of the Asteroid Deflection Research Center at Iowa State University, Dr. Bong Wie (who had published kinetic impactor deflection studies previously), began to study strategies that could deal with 50-to-500-metre-diameter (200–1,600 ft) objects when the time to Earth impact was less than one year. He concluded that to provide the required energy, a nuclear …

Planet V is a hypothetical fifth terrestrial planet posited by NASA scientists John Chambers and Jack J. Lissauer to have once existed between Mars and the asteroid belt.In their hypothesis the Late Heavy Bombardment of the Hadean era began after perturbations from the other terrestrial planets caused Planet V's orbit to cross into the asteroid belt. Chambers and Lissauer …

Panico a Vienna il 9 maggio 1873 durante il venerdì nero del crollo della borsa valori. La grande depressione del XIX secolo, detta anche lunga depressione, fu una crisi economica – la prima a essere chiamata tale per vastità di portata ed estensione temporale in cui dispiegò i suoi effetti – che ebbe inizio a Vienna nel 1873 e si propagò anche negli Stati Uniti d'America durante la ...

The moon always shows the same side to Earth. Astronomers call this phenomenon tidal locking.This means that half of it can never be seen from Earth. The side facing away from Earth is called the far side or dark side of the Moon even though the sun does shine on it—we just never see it lit.. History of exploring the Moon

Hetch Hetchy is a valley, a reservoir, and a water system in California in the United States.The glacial Hetch Hetchy Valley lies in the northwestern part of Yosemite National Park and is drained by the Tuolumne River.For thousands of years before the arrival of settlers from the United States in the 1850s, the valley was inhabited by Native Americans who practiced …

The asteroid belt is a torus-shaped region in the Solar System, located roughly between the orbits of the planets Jupiter and Mars.It contains a great many solid, irregularly shaped bodies, of many sizes, but much smaller than planets, called asteroids or minor planets.This asteroid belt is also called the main asteroid belt or main belt to distinguish it from other asteroid populations …

In quantum mechanics, perturbation theory is a set of approximation schemes directly related to mathematical perturbation for describing a complicated quantum system in terms of a simpler one. The idea is to start with a simple system for which a mathematical solution is known, and add an additional "perturbing" Hamiltonian representing a weak disturbance to the system.

The first artificial object to fly by the Moon was uncrewed Soviet probe Luna 1 on January 4, 1959 and went on to be the first probe to reach a heliocentric orbit around the Sun. Few knew that Luna 1 was designed to impact the surface of the Moon.. The first probe to impact the surface of the Moon was the Soviet probe Luna 2, which made a hard landing on September 14, 1959, at …
