A Near-earth Object, Asteroid 1998 QE2, Is Now Hurtling Towards Earth

Asteroid 1998 QE2 - 1

A near-earth object labeled Asteroid 1998 QE2, is now hurtling towards earth.

The asteroid about 1.7 miles (2.7 kilometers) or nine Queen Elizabeth 2 ship-lengths in size in length has the physical mass to potentially knockout life on Earth. However, we are safe as it is just flying by.

The orbit of asteroid 1998 QE2

On May 31, 2013, at 20:59 UTC (1:59 p.m. Pacific / 4:59 p.m. Eastern) this asteroid will pass within 3.6 million miles (5.8 million km) of Earth – about 15 times the distance to the Moon. While this may seem a great distance for the layman, in astronomical terms it is a mere stone’s throw away. This is the closest approach the asteroid will make to Earth for at least the next two centuries.

The Massachusetts Institute of Technology Lincoln Near Earth Asteroid Research (LINEAR) program near Socorro, New Mexico, discovered this asteroid on August 19, 1998. It is officially known as Asteroid 1998 QE2. It is not named in honor of Queen Elizabeth II, or after that 12-decked, transatlantic-crossing flagship for the Cunard Line. The name was assigned by the NASA-supported Minor Planet Center in Cambridge, Massachusetts, USA. This institute assigns each newly discovered asteroid a provisional designation starting with the year of first detection, along with an alphanumeric code showing the half-month it was discovered, and the sequence within that half-month.

Though this asteroid is not of much interest to those astronomers and scientists on the lookout for hazardous asteroids, it is of interest to those who dabble in radar astronomy and have a 230-foot (70-meter) or larger radar telescopes at their disposal.

Radar astronomer Lance Benner, the principal investigator for the Goldstone radar observations from NASA’s Jet Propulsion Laboratory in Pasadena, California said: “Asteroid 1998 QE2 will be an outstanding radar imaging target at Goldstone and Arecibo and we expect to obtain a series of high-resolution images that could reveal a wealth of surface features … Whenever an asteroid approaches this closely, it provides an important scientific opportunity to study it in detail to understand its size, shape, rotation, surface features, and what they can tell us about its origin. We will also use new radar measurements of the asteroid’s distance and velocity to improve our calculation of its orbit and compute its motion farther into the future than we could otherwise.”

Asteroid 1998 QE2

Asteroids come in various sizes and shapes: dog bones, bowling pins, spheroids, diamonds, muffins, potatoes, etc. Between May 30 and June 9, radar astronomers using NASA’s 230-foot-wide (70 meter) Deep Space Network antenna at Goldstone, California, and the Arecibo Observatory in Puerto Rico, are planning an extensive campaign of observations. The two telescopes with complementary imaging capabilities will enable astronomers to study 1998 QE2 and what it looks like during its brief flyby.
