The rate may drop below 60 beats per minute in people who exercise routinely or take medicines that slow the heart.

Density, mass, and volume. Venus is a rocky, terrestrial planet like Earth, and likely formed the same way at the same time. It has a mass of 4.87 trillion trillion kilograms, about 82 percent that of its sister planet. Like its size, its density is comparable to Earth at 5.243 grams per cubic centimeter.ften called Earth's sister planet, Venus is the closest in size, with a mass of more than 80 percent that of our planet and a diameter of only a few miles less.
