The following table shows measures of %2's distance to the sun at certain times ($t = 0$ represents the time when the planet was closest to the sun).

Time $\bold{t}$ (years) \t Distance $\bold{r}$ (million km) \\ %4[0] \t %5[0]
\\ %4[1] \t %5[1]
\\ %4[2] \t %5[2]
\\ %4[3] \t %5[3]
\\ %4[4] \t %5[4]
\\ %4[5] \t %5[5]
\\ %4[6] \t %5[6]
\\ %4[7] \t %5[7]
\\ %4[8] \t %5[8]
\\ %4[9] \t %5[9]
\\ %4[10] \t %5[10]
\\ %4[11] \t %5[11]
\\ %4[12] \t %5[12]

Figures are rounded and based on the planet's characteristics as documented in, say, wikipedia.org.
