Venus is the second planet from the Sun after Mercury, followed by the Earth. Its mass is 81.5% of that of the Earth, 85.7% the volume and ~90% by surface area. Its surface gravity is 8.87 m/s 2 ...

While Venus passes between the Earth and Sun every 19.5 months, it's only about every eight or so years that the planet becomes visible both after sunset and before sunrise, according to the ...
