What’s cooler than an asteroid? How about an astroid with it’s own moon!
The asteroid is 1998 QE2 and NASA scientists have used radar technology to take images of it, as seen at the top of this article. This type of asteroid is known as a binary asteroid and some even have two orbiting moons, those are referred to as triple systems. This asteroid is in the Near-Earth population of asteroids and is about 1.7 miles (2.7 kilometers) in diameter.
The image was taken May 29th, 2013 using the Deep Space Network antenna in Goldstone California which is very large.
The antenna itself is 70 meters or 230 feet in diameter and that makes it the largest and most sensitive Deep Space Network antenna on Earth. The DSN antenna is capable of tracking a spacecraft travelling more than 16 billion kilometers (10 billion miles) from Earth.
