Appendix 1. SI Units
We typically denote numerical values in scientific notation with a number in the interval $[1,10)$,
multiplied by a power of ten, followed by a combination of the following units:

Appendix 3. The Solar System
The solar system has $1.0014$ solar masses,
which amounts to about $2 \times 10^{30}\, \, \text{kg}$.
The Earth-Sun distance is $1 \, \text{AU} \simeq 500 \, \text{light second} \simeq 1.5 \times 10^{11}\, \, \text{m}$.
