It is called twin of earth because of its similar size to earth.

And its diameter is also slightly smaller than earth.and gravity of Venus is 90% of earth.

Venus has approximately the same mass as the Earth yet it is a hellish place where surface temperatures are over 400C and the surface pressure is a hundred times that on Earth. The key to understanding Venus lies in its atmosphere, which is much thicker than Earth's.

They happen to be about the same size, and have adjacent orbits in the solar system. At a time when little more was known about Venus, it was dubbed "Earth's twin". People seriously expected to find jungles or swamps there.

And also they are very similar gravity, and bulk composition
,but not temperature, atmosphere,
or ability to support life.

Its mass is 82% of Earth's mass, its density is 89% of Earth's density , and its diameter is 95% of Earth's diameter.
