3031

3031 is a natural number that follows 3030 and precedes 3032. It is an odd composite number with the prime factorization 7 × 433. In base-10 notation its digits are 3, 0, 3, and 1; the number is not a palindrome. The sum of its digits is 7, so it is not divisible by 3. It lies between the squares 55^2 = 3025 and 56^2 = 3136, and it is neither a perfect square nor a perfect cube. Like many integers, it can be expressed in different bases, and its arithmetic properties are of interest in recreational number theory.

In the context of calendars, 3031 AD would be a year in the fourth millennium. Under the proleptic Gregorian calendar, 3031 is not a leap year, so it would have 365 days. The year would begin on a day of the week determined by the calendar cycle in effect, with common-year shifts occurring in the usual manner for non-leap years.

In astronomy, 3031 is the designation of a minor planet (asteroid). The numeral is assigned by the Minor Planet Center after an object's orbit has been observed sufficiently to determine a reliable path. Such objects are cataloged in lists of the Solar System’s minor planets, and many belong to the main asteroid belt between Mars and Jupiter. The numerical designation uniquely identifies the object within the catalog; a proper name may be added later if one is given.
