(9927) Tyutchev is an asteroid of the main inner belt that was discovered by the Soviet astronomer Lyudmyla Karachkina on October 3, 1981 at the Crimean Observatory in Nautschnyj ( IAU code 095).
The asteroid's solar orbit is strongly elliptical with an eccentricity of 0.2440 . At the point of its orbit closest to the Sun, Tyutchev comes (9927) very close to the outermost point of Mars' orbit (to about 0.009 AU or about 1.3 million kilometers), but does not cross it.
(9927) Tyutchev was named on May 4, 1999 after the Russian poet Fyodor Ivanovich Tjuttschew (1803–1873).
