(527603) 2007 VJ305 is a minor planet (also known as an asteroid) discovered on November 4, 2007, by the Catalina Sky Survey. The numerical designation (527603) indicates that it is the 527603rd minor planet to have its orbit determined. The designation "2007 VJ305" is a provisional designation assigned based on the year of discovery (2007), the half-month within that year (V), and the sequential letter (J) and number (305) assigned to discoveries made during that period.
The exact orbital characteristics and physical properties of (527603) 2007 VJ305 would require accessing astronomical databases, such as the Minor Planet Center database, which contains detailed information on discovered minor planets. These databases provide information about the asteroid's orbital elements (e.g., semi-major axis, eccentricity, inclination), estimated size, and rotational period, when available. Without directly querying these databases, only general information related to asteroid nomenclature and discovery can be provided.
