The coordinates of the Sun would be diametrically opposite Proxima Centauri, at α=02^h 29^m 42.9487^s, δ=+62° 40′ 46.141″. The absolute magnitude M_v of the Sun is 4.83, so at a parallax π of 0.77199 the apparent magnitude m is given by 4.83 − 5(log₁₀(0.77199) + 1) = 0.40. See: Tayler, Roger John (1994). The Stars: Their Structure and Evolution. Cambridge University Press. p. 16. ISBN 978-0-521-45885-6.
For a star south of the zenith, the angle to the zenith is equal to the Latitude minus the Declination. The star is hidden from sight when the zenith angle is 90° or more, i.e., below the horizon. Thus, for Proxima Centauri:
Highest latitude = 90° + (−62.68°) = 27.32°.

The density (ρ) is given by the mass divided by the volume. Relative to the Sun, therefore, the density is $\rho ={\frac {M}{M_{\odot }}}\cdot \left({\frac {R}{R_{\odot }}}\right)^{-3}\cdot \rho _{\odot }$ $\rho ={\frac {M}{M_{\odot }}}\cdot \left({\frac {R}{R_{\odot }}}\right)^{-3}\cdot \rho _{\odot }$ = 0.122 · 0.154⁻³ · (1.41 × 10³ kg/m³) = 33.4 · (1.41 × 10³ kg/m³) = 4.71 × 10⁴ kg/m³, where $\rho _{\odot }$ $\rho _{\odot }$ is the average solar density.

The density (ρ) is given by the mass divided by the volume. Relative to the Sun, therefore, the density is $\rho ={\frac {M}{M_{\odot }}}\cdot \left({\frac {R}{R_{\odot }}}\right)^{-3}\cdot \rho _{\odot }$ $\rho ={\frac {M}{M_{\odot }}}\cdot \left({\frac {R}{R_{\odot }}}\right)^{-3}\cdot \rho _{\odot }$ = 0.122 · 0.154⁻³ · (1.41 × 10³ kg/m³) = 33.4 · (1.41 × 10³ kg/m³) = 4.71 × 10⁴ kg/m³, where $\rho _{\odot }$ $\rho _{\odot }$ is the average solar density.
