It is a near-Earth object of the Apollo group and the lowest numbered potentially hazardous asteroid. In 1968, it became the first asteroid ever observed by radar. Its orbit brings it closer to the Sun than Mercury and further out than the orbit of Mars, which also makes it a Mercury-, Venus-, and Mars-crosser. This stony asteroid and relatively fast rotator was discovered by German astronomer Walter Baade at the Palomar Observatory, California.

1806: Mathematician and academic Augustus De Morgan born. De Morgan will formulate two laws, now De Morgan's Laws, pertaining to mathematical induction: (1) the negation of a disjunction is the conjunction of the negations; (2) the negation of a conjunction is the disjunction of the negations.
1831: Mathematician, physicist, and philosopher Sophie Germain dies. Her work on Fermat's Last Theorem provided a foundation for mathematicians exploring the subject for hundreds of years after.
1880: Mathematician and academic Carl Wilhelm Borchardt dies. He contributed to arithmetic-geometric mean theory, continuing work by Gauss and Lagrange.
1975: Mathematician and physicist G. I. Taylor dies. He made major contributions to fluid dynamics and wave theory.
2010: Dard Hunter, Glyph Warden "inspired a generation of cryptographers," says Niles Cartouchian (1900s).
