Tikhonravov may refer to:
Mikhail Klavdievich Tikhonravov was a Soviet aerospace engineer and scientist who was a pioneer of spacecraft design and rocketry.
Nikolai Savvich Tikhonravov was a Russian philologist and historian of Russian literature.
Tikhonravov is a large, eroded crater in the Arabia quadrangle of Mars. It is 344 kilometres (214 mi) in diameter and was named after Mikhail Tikhonravov, a Russian rocket scientist. Tikhonravov is believed to have once held a giant lake that drained into the 4500 km long Naktong-Scamander-Mamers lake-chain system. An inflow and outflow channel has been identified. Many craters once contained lakes.

Konstantin Petrovich Feoktistov was a Soviet cosmonaut and an eminent space engineer. Feoktistov also wrote several books on space technology and exploration. The Feoktistov crater on the far side of the Moon is named in his honor.
Kara is a meteor crater in the Yugorsky Peninsula, Nenetsia, Russia.
Obolon' crater is a 20 km (12 mi) diameter buried meteorite impact crater situated about 200 km (120 mi) southeast of Kiev in Ukraine . The site has been drilled, which revealed the presence of shocked minerals and impact melt rock; the high chlorine content of the latter suggesting that the area was covered by shallow sea at the time of impact. One estimate puts the age at 169 ± 7 million years.
The Popigai crater in Siberia, Russia, is tied with the Manicouagan Crater as the fourth largest verified impact crater on Earth. A large bolide impact created the 100-kilometre (62 mi) diameter crater approximately 35 million years ago during the late Eocene epoch. It is conjectured that it may have influenced the Eocene–Oligocene extinction event.
The far side of the Moon is the hemisphere of the Moon that always faces away from Earth. The far side's terrain is rugged with a multitude of impact craters and relatively few flat lunar maria. It has one of the largest craters in the Solar System, the South Pole–Aitken basin. Both sides of the Moon experience two weeks of sunlight followed by two weeks of night; the far side is sometimes called the "dark side of the Moon", meaning unseen rather than lacking light.
Boris is a tiny lunar impact crater that is located on the Mare Imbrium, to the northeast of the crater Delisle. It lies near the southwest extremity of a sinuous rille that is designated Rima Delisle. This rille meanders to the northeast, towards the crater Heis, before vanishing into the lunar mare. The name Boris is a common Russian male given name; the crater is not named after a specific person.
Arabia Terra is a large upland region in the north of Mars that lies mostly in the Arabia quadrangle, but a small part is in the Mare Acidalium quadrangle. It is densely cratered and heavily eroded. This battered topography indicates great age, and Arabia Terra is presumed to be one of the oldest terrains on the planet. It covers as much as 4,500 km (2,800 mi) at its longest extent, centered roughly at 21°N 6°E with its eastern and southern regions rising 4 km (13,000 ft) above the north-west. Alongside its many craters, canyons wind through the Arabia Terra, many emptying into the large northern lowlands of the planet, which borders Arabia Terra to the north.
The Arabia quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The Arabia quadrangle is also referred to as MC-12.
Dejnev is a crater on Mars, located in the Memnonia quadrangle at 25.1° south latitude and 164.8° west longitude. It measures approximately 152 kilometer in diameter. It was named after Russian geographer, explorer, and navigator Semyon Dezhnev (1605–1673). The name was adopted by IAU's Working Group for Planetary System Nomenclature in 1985.
Fesenkov Crater is an impact crater in the Lunae Palus quadrangle of Mars. It is located at 21.8° N and 86.7° W. It was named after Vasilii G. Fesenkov, a Russian astrophysicist (1889–1972).
Jezža is a crater on Mars, located at 48.8°S 38°W in the Argyre quadrangle. It measures approximately 9.1 kilometers in diameter and was named after a town in Russia. Jezža is on the floor of Argyre Planitia between the craters Hooke and Galle.
Arkhangelsky Crater is a crater in the Argyre quadrangle of Mars, located at 41.4° S and 24.8° W. It is 117 km across and was named after the Russian geologist A.D. Arkhangelsky.
Udzha is an impact crater on Mars, that measures 45 kilometer in diameter, but has been almost entirely covered by layers of ice and dust. Only the highest part of the crater rim rises above the polar deposits and hint at its circular form. Udzha Crater is located at 81.8 degrees north latitude, 77.2 degrees east longitude on Mars. It was named after a village in northern Russia.
Sharonov is an impact crater in the Lunae Palus quadrangle of Mars, located at 27.3°N 301.5°E. It is 100.0 km (62.1 mi) in diameter and was named after Vsevolod V. Sharonov, a Russian astronomer (1901-1964). Sharonov is situated within the outflow channel system Kasei Valles, whose flows were divided into two main branches that bracket the crater.
Schmidt is an impact crater on Mars, located in the Mare Australe quadrangle at 72.3°S latitude and 78.1°W longitude. It measures approximately 201 kilometers in diameter. It was named after German astronomer J. F. Julius Schmidt and Russian geophysicist Otto Schmidt. The naming was officially approved by the International Astronomical Union (IAU) Working Group for Planetary System Nomenclature in 1973.
