An impactor is the object or 'tool' making the impaction. For example, If a crater was to be made, the meteor is the impactor, the crater is the impaction, and the ejecta is the loose debris.

Asteroids, meteorites or comets are impactors that form impact craters on the Earth and other bodies throughout the solar system. Obviously, the Earth for instance, has to cross an impactor's orbit or vice versa. The size of the impactor hitting the Earth depends on the type of crater that can occur and also the other factors- · the velocity of the impactor · composition of the impactor · composition of the target rock · the strength and porosity of the impactor · angle of impact · gravity of the target planet For more on craters try- www.weirdwarp.com
From the impact of fast moving objects with a surface. The kinetic energy of the impactor excavates a crater with an inverted, raised rim and forms an ejector plume leaving a crater and, if the impactor is sufficiently large or fast, a central mountain peak.
An impact crater is typically much larger than the impactor that created it. The size of the crater depends on various factors such as the velocity and angle of impact, as well as the physical properties of the impacting object and the target surface. In general, the diameter of an impact crater can range from a few times to several tens of times larger than the diameter of the impactor.
Basically Cydia Extender is a segment of Cydia Impactor. As in it is a part of the most recent Cydia Impactor release. And also Cydia Extender installs as its individual application on iOS devices such as iPhone/ iPad/ iPod touch. Cydia Extender has been designed to re-sign automatically to the applications that are not downloaded from the original app store. The main feature of Cydia Extender is that when it signed in to an application, it remains signed in for the rest of the time. So you can quickly sign-in to an app automatically whenever you want.
Is called a bolide or impactor and any fragments that survive the collision with the atmosphere or ground are called meteorites.

The impact craters themselves are stationary; they don't move. The impactor that MADE the craters was moving quite rapidly, but we don't know exactly how fast any particular impactor was, since we didn't measure it. However, the meteors in the 2009 Perseid meteor shower were going at 130,000 miles per hour when they entered the Earth's atmosphere. So the lunar impactors were probably going somewhere near that velocity.
All impact craters are circular, no matter what the shape of the impactor or the angle of impact. Of the options provided in the Discussion page, only choice "B" is accurate. The energy released in the impact melted the impactor - and the surface - to the point of being fluid, or at least malleable. Option "D", that the craters were formed early in the Moon's history, is probably also true, but the circular shape of the craters isn't dependent on this.
