asteroid 2002 nn4 wikipedia


A variability of the visual brightness was also detected which could fit to 7.9 h or 15.8 h rotational period (the distinction between single or double-peaked curved could not be made with confidence). (89959) 2002 NT 7 (prov. The adjacent diagrams show polar and ecliptic views of the orbits of the two cubewanos. "In short, 2002 NN4 is a very well-known asteroid with a known orbit that will pass Earth at a (very) safe distance," wrote Ian J. O'Neill of NASA's Jet Propulsion Laboratory. Despite inflammatory press reports, the object had a "low probability" of impact of approximately one in a million for 1 February 2019. [15], 2002 TX300 occulted a relatively bright apparent magnitude 13.1 star in the constellation of Andromeda on 9 October 2009.

It is about the size of the Empire State Building at New York City, which is more than 1,400 feet tall …

“There is no danger the asteroid will hit the Earth,” NASA said. While smaller space rocks are difficult to track, they are unlikely to cause major damage. 2002 TX 300 has the most eccentric and inclined orbit of the three. Thankfully, it is expected to remain a safe distance away. SpaceX launch a ‘turning point’ for new space age, Your California Privacy Rights/Privacy Policy. [14] Because 2002 TX300 is a member of the Haumea family, it is assumed to have an albedo of around 0.7, which would result in a diameter of about 360 kilometres (220 mi). [2] [3] It has a well determined orbit with an observation arc of 64 years including precovery images by Palomar Observatory dating back to 1954. Named 2002 NN4, the asteroid is more than 1,000 feet across and will swing by near enough to make it onto NASA's "close approach" list, which documents near-Earth objects and the dates they approach our planet.

[5] In 2008, it was considered to be a dwarf planet based on its lightcurve amplitude and the assumption that it was larger than 450 kilometres (280 mi) in diameter.
Eksentrisitas orbit asteroid ini tercatat sebesar 0.434, sementara magnitudo mutlaknya adalah 20.0.. Pembentukan. Other mid-sized cubewanos follow similar orbits as well, notably 2002 UX25 and 2002 AW197. [16] The RA and declination for this event was about 00 37 13.64 +28 22 23.2.: detailed information for observers was made available.

The object, together with other members of the family ((19308) 1996 TO66, (24835) 1995 SM55, (120178) 2003 OP32 and (145453) 2005 RR43), would be created from ice mantle ejected from the proto-Haumea as result of a collision with another large (around 1,660 kilometres (1,030 mi)) body.[22].

The diameter of the asteroid is only about 20–100 metres (70–300 ft). © 2020 USA TODAY, a division of Gannett Satellite Information Network, LLC. It has been observed 303 times, with precovery images back to 1954. [3], 2002 NT7 became the first object observed by NASA's NEO program to be assigned a positive rating on both the Torino Scale and the Palermo Technical Impact Hazard Scale,[5] for a small chance of an impact on 1 February 2019, although it has now been known for years that it would pass Earth at roughly 0.4078 AU (61,010,000 km; 37,910,000 mi) on 13 January 2019 with an uncertainty region of about ±108 km.[6].

(55636) 2002 TX300 is a bright Kuiper belt object in the outer Solar System estimated to be about 286 kilometres (178 mi) in diameter. 2002 NT7 was removed from the Sentry Risk Table on 1 August 2002, (23 days after discovery) so there is no risk of an impact by it in the next 100 years.
163348 (2002 NN4) is a very small asteroid whose orbit could bring it in close proximity to Earth.

Named 2002 NN4, the asteroid is more than 1,000 feet across and will swing by near enough to make it onto NASA's "close approach" list, which documents near-Earth objects and … The proportion of highly processed organic materials (tholins), typically present on numerous trans-Neptunian objects, is very low. (89959) 2002 NT7 (prov. (163348) 2002 NN4 adalah sebuah asteroid.Asteroid ini merupakan bagian dari asteroid Aten, yang terletak dekat dengan bumi. [16] This event was visible from Australia, possibly New Zealand, and the southern United States and Mexico. Asteroids like 2002 NN4 cause concern because of their potential impact on Earth. A Near-Earth Object (NEO), the asteroid is called 163348 (2002 NN4) and is classified as a Potentially Hazardous Asteroid (PHA).

Asteroid ini merupakan bagian dari asteroid Aten, yang terletak dekat dengan bumi.

designation: 2002 NT7) is a near-Earth object with a diameter of 1.4 kilometers and potentially hazardous asteroid of the Apollo group. Common physical characteristics with the dwarf planet Haumea together with similar orbit elements[21] led to suggestion that 2002 TX300 was a member of the Haumean collisional family. As per NASA’s Jet Propulsion Laboratory (JPL), the asteroid 2002 NN4 is more remarkable for its size, with an estimated diameter between 820 feet and 1,870 feet. What are Near-Earth Objects (NEOs), why are they studied?

Thankfully, this particular space rock is predicted to stay more than 3 million miles away — or 13 times farther from us than the Moon, NASA said in an emailed statement to USA TODAY.

[9] On 13 January 2019, the asteroid safely passed 0.4078 AU (61,010,000 km; 37,910,000 mi) from Earth with a 3-sigma uncertainty region of about ±108 km. HIGHLIGHTS 2002 NN4 Asteroid का आकार 0.250-0.570 किलोमीटर के बीच का है अंदाजा लगाया जा रहा है कि यह पृथ्वी के करीब 5 किमी दूर से निकल जाएगा 177 फीट के Asteroid … [4] It is a large member of the Haumea family that was discovered on 15 October 2002 by the Near-Earth Asteroid Tracking (NEAT) program.[1]. [17] The occultation produced a diameter of 286 kilometres (178 mi), suggesting an albedo of about 0.88. [6], On 30 January 2020, the asteroid safety passed 0.02718 AU (4,066,000 km; 2,527,000 mi) from 2 Pallas. The spectrum in the visible and near-infrared rages is very similar to that of Charon, characterized by neutral to blue slope (1%/1000 Å) with deep (60%) water absorption bands at 1.5 and 2.0 μm. The changes in brightness are quite close to the error margin and could also be due to an irregular shape.[10]. Talk:(163348) 2002 NN4. [19] Mineralogical analysis indicates a substantial fraction of large ice (H2O) particles.
