Future
Dynamically, the Kreutz Sungrazers might continue to be recognised as a distinct family for many thousands of years yet. Eventually their orbits will be dispersed by gravitational perturbations, although depending on the rate of fragmentation of the constituent parts, the group might be completely destroyed before it is gravitationally dispersed. The continuing discovery of large numbers of the smaller members of the family by SOHO will undoubtedly lead to a greater understanding of how comets break up to form families.
It is not possible to estimate the chances of another very bright Kreutz comet arriving in the near future, but given that at least 10 have reached naked eye visibility over the last 200 years, another great comet from the Kreutz family seems almost certain to arrive at some point. Comet White–Ortiz–Bolelli in 1970 reached an apparent magnitude of 1. In December 2011, Kreutz sungrazer C/2011 W3 (Lovejoy) survived its perihelion passage and had an apparent magnitude of −3.

Famous quotes containing the word future:
“The present hour is always wealthiest when it is poorer than the future ones, as that is the pleasantest site which affords the pleasantest prospects.”
—Henry David Thoreau (1817–1862)
“‘Tis the world-old way of the rain
