Your arms will be parallel to the ground. a centimetre (a hundredth of a metre) a millimetre (a thousandth of a metre) a micrometre (a millionth of a metre) As part of the International System of Units (SI), the standard symbol for nanometre is nm. Due to its large surface, the 30-meter telescope is highly sensitive and well-adapted to detect weak sources. In fact, Mercury's mass is approximately 3.3 x 10 23 kg (5.5% the mass of Earth) which means that its density - at 5.427 g/cm 3 - is the second highest of any planet in the Solar System .
