The two, with spectral classes nearly identical to that of Na'ir al Saif, are hurtling away from each other in opposite directions at 200 kilometers per second. Recent calculations of the movements of the stars explain the two runaways and Na'ir al Saif as well, showing that they were all kicked out of the Trapezium Cluster. Some 2.5 million years ago, the Trapezium region held a pair of tightly-knit double stars. In a very close encounter between the two binaries, two of the four stars were ejected, while the remaining two, instead of being evicted, stayed more or less behind in highly eccentric embrace. Na'ir al Saif still lingers near the Orion Nebula, marking the place of the violent event.
More violence is in store, as the star is fated to explode as a supernova.
