How big is Pluto vs Mercury?

In case you’re wondering, though, Mercury is still significantly larger than the dwarf planet Pluto: Pluto’s equatorial diameter is just 2,302 km, about half Mercury’s width.

What is the diameter of Mercury’s core in KM?

2,060 km
With a size of 2,060 km, Mercury’s core is 50 km larger than previously thought.

What is the relative size of the planet Mercury?

With a radius of 1,516 miles (2,440 kilometers), Mercury is a little more than 1/3 the width of Earth. If Earth were the size of a nickel, Mercury would be about as big as a blueberry. From an average distance of 36 million miles (58 million kilometers), Mercury is 0.4 astronomical units away from the Sun.

What is the meaning of the term nominal diameter?

Nominal Diameter is also known as the mean or average outside diameter and is represented by DN. It is neither equal to the inner diameter (ID) nor the outer diameter (OD) of the pipe. Nominal is a word that denotes non-specificity and in this case, identifies the approximate inner diameter with a non-dimensional number.

How many micrometres are in a millimetre of mercury?

Each millimetre of mercury can be divided into 1000 micrometres of mercury, denoted μmHg or simply microns. The precision of modern transducers is often insufficient to show the difference between the torr and the millimetre of mercury.

How big is a millimetre of mercury in pascals?

A millimetre of mercury is a manometric unit of pressure, formerly defined as the extra pressure generated by a column of mercury one millimetre high, and currently defined as exactly 133.322387415 pascals. It is denoted mmHg or mm Hg.

What’s the difference between Torr and millimetre of mercury?

The precision of modern transducers is often insufficient to show the difference between the torr and the millimetre of mercury. The torr is about one part in seven million or 0.000015% less. By the same factor, a millitorr is slightly less than a micrometre of mercury. In medicine, pressure is still generally measured in millimetres of mercury.
