1. Compare - without doubt the biggest advantage that the Solar Mass offers shoppers today is the ability to compare thousands of Solar Mass at a time. This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.

2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about

The solar mass is a standard way to express mass in astronomy, used to describe the masses of other stars and galaxy. It is equal to the mass of the Sun, about two Names of large numbers kilograms or about 332,950 times the mass of the Earth. Its conventional symbol and value are:

M_{\bigodot}=1.9891\times10^{30}\hbox{ kg}

The solar mass can be determined from the length of the year, the distance of the Earth to the Sun (the astronomical unit) (AU), and the gravitational constant (G) as

M_\bigodot=\frac{4 \pi^2 \times (1{\rm AU})^3}{G\times(1{\rm yr})^2}.

Until recently, neither the AU nor the gravitational constant was precisely known. However, a determination of the relative mass of another planet in the Solar System or of a Binary_star#Use_in_astrophysics in units of solar masses does not depend on these poorly known constants. So it was useful to express these masses in units of solar masses (see Gaussian gravitational constant). Today, the AU is extremely well measured using interplanetary radar and G is well measured, but the solar mass persists as one of astronomy's arcane historical Convention (norm).
