Research
The observed peculiarities in the Hildas' motion are based on data for a few hundred objects known to date and generate still more questions. Further observations are needed to expand on the list of Hildas. Such observations are most favorable when the Earth is near conjunction with the mid-sides of the Hildas Triangle. These moments occur each 4 and 1/3 months. In these circumstances the brilliance of objects of similar size could run up to 2.5 magnitudes as compared to the apexes.
The Hildas traverse regions of the Solar system from approximately 2 AU up to Jupiter's orbit. This entails a variety of physical conditions and the neighborhood of various groups of asteroids. On further observation some theories on the Hildas may have to be revised.

Famous quotes containing the word research:
“I did my research and decided I just had to live it.”
—Karina O’Malley, U.S. sociologist and educator. As quoted in the Chronicle of Higher Education, p. A5 (September 16, 1992)
“To be sure, nothing is more important to the integrity of the universities ... than a rigorously enforced divorce from war- oriented research and all connected enterprises.”
—Hannah Arendt (1906–1975)
“Men talk, but rarely about anything personal. Recent research on friendship ... has shown that male relationships are based on shared activities: men tend to do things together rather than simply be together.... Female friendships, particularly close friendships, are usually based on self-disclosure, or on talking about intimate aspects of their lives.”
—Bettina Arndt (20th century)
