Eyeglasses made of nylon were introduced in the late 1940s. Because of brittleness and other problems, eyeglass manufacturers switched to blended nylon (polyamides, co-polyamides and gliamides). Today's blended nylon frames are both strong and lightweight.
Venus is the closest size to Earth and is sometimes called Earth's sister planet.. Its diameter is 95% of Earth's but its mass is only 81% as much.
The two planets of the solar system closest in g-value at their surface to Earth, are Venus and Saturn. Venus is slightly less (8.87 N/kg), Saturn is slightly more (10.44 N/kg). So you cannot just tell by looking at the values. As it turns out though, Saturn's value is closer.
