Radar has been used to map the surface of Venus
Several spacecraft have observed Venus, including NASA's Magellan spacecraft which mapped the planet's surface with radar, and the European Space Agency's Venus Express which studied the planet's atmosphere and surface. The Soviet Union's Venera program also sent several landers and probes to Venus in the 1970s and 1980s.
A good hypothesis for Venus could be: "Increased volcanic activity on Venus has contributed to the thick atmosphere and extreme surface temperatures observed on the planet."
Yes, Venus has been hit by meteoroids, but its thick atmosphere burns up most smaller meteoroids before they reach the surface. The impact craters observed on Venus are thought to have been caused by larger asteroids or comets colliding with the planet's surface.
Galileo observed phases of Venus, which were only possible if Venus orbited the Sun and not Earth, supporting the heliocentric model of the solar system proposed by Copernicus. This observation was a key piece of evidence in favor of the heliocentric theory.
Jupiter, at the surface anyway. Venus has the hottest surface temperature of all the planets.

The surface of Venus is unobservable due to the thick cloud cover. Some Russian Venera spacecraft have landed there to get a glimpse of the rocky surface, and the entire planet has been mapped by radar.

The "topography" of Venus is the three dimensional shape of the surface of Venus.
The atmosphere on the surface of Venus is cloudy.
Venus has a solid rocky surface.
Venus has craters on it's surface!
The first spacecraft to observe Venus was the Venera 3 in 1962.
the surface feature of Venus are craters, meteorites and mostly acid water
The surface area of the planet Venus is 4.60×108 km2.
Venus surface is a dry desertscape with many slab-like rocks
