Boötes

Constellation model home > Boötes

This is a 3D model of the constellation Boötes, The Herdsman. The resolution is 9x9x9 places, so the star placements are to the closest XYZ point in the 9x9x9 volume. Depth is relative to the star’s actual distance relative to one another. Relative to the star placements, the observer (Earth) would be outside of the model somewhere near x: 5, y: 5, z: -1. For best viewing hold the model at arm’s length to minimize distortion due to parallax. The model space is 9" x 9" x 9" on a 12" x 12" base, and is built from cardboard, bamboo skewers and cord.

1. α — 37 ly — Arcturus, vis mag: -0.05 — 621
2. ε — 236 ly — Vis mag: 2.37 —449
3. η — 37 ly — Vis mag: 2.68 — 721
4. γ — 85 ly — Vis mag: 3.04 — 563 (2.17)
5. δ — 117 ly — Vis mag: 3.46 — 354 (3.61)
6. β — 219 ly — Vis mag: 3.49 — 479 (8.23)
7. ρ — 149 ly — Vis mag: 3.57 — 546 (5.06)
8. ζ — 180 ly — Vis mag: 3.78 — 417 (6.47)
9. θ — 48 ly — Vis mag: 4.04–591 (0.49)

We can go ahead and place α, η at z=1, being the closest, both at 37 ly. And also ε at z=9, as it is the farthest object in the set at 236 ly. Total depth of model = 236–37=199 ly.

This distributes nicely throughout the depth, we will have a nice stereoscopic effect.
