Problem

(a) Estimate the height (zz) above or below the Galactic plane for both M13 (ℓ=59.0∘\ell = 59.0^\circ, b=40.9∘b = 40.9^\circ) and the Orion nebula (ℓ=209.0∘\ell = 209.0^\circ, b=−19.4∘b = -19.4^\circ). M13 and the Orion Nebula are 7 kpc and 450 pc from Earth, respectively. (b) To which components of the Galaxy do these objects probably belong? Explain your answers.
