14335 Alexosipov, provisional designation , is a stony Flora
asteroid
An asteroid is a minor planet of the inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere.

Physical characteristics
''Alexosipov'' has been characterized as a common
S-type asteroid
S-type asteroids are asteroids with a spectral type that is indicative of a siliceous (i.e. stony) mineralogical composition, hence the name. They have relatively high density. Approximately 17% of asteroids are of this type, making it the second ...

Astronomical Observatory of Kyiv National University in Kiev, Ukraine. He is described as a skilled teacher for many generations of students.
The approved naming citation was published by the
