| 31. | M107 is close to the galactic plane at a distance of about 20, 900 light-years from Earth.
|
| 32. | Run that another few gigayears and you should have a well-defined galactic plane and maybe spiral arms.
|
| 33. | This orbit carries it no more than about 330 ly ( 100 pc ) above the galactic plane.
|
| 34. | This survey is the first large-area, systematic and uniform survey of the galactic plane in the millimeter continuum.
|
| 35. | The zero point for supergalactic longitude is defined by the intersection of this plane with the galactic plane.
|
| 36. | A tick mark at the end of each line gives the Z coordinate perpendicular to the galactic plane.
|
| 37. | However the field is closer to the galactic plane than the HDF-N, meaning that it contains more galactic stars.
|
| 38. | The density estimate varies across space, with the density decreasing rapidly in the direction out of the galactic plane.
|
| 39. | The Galactic plane is inclined by about 60 degrees to the ecliptic ( the plane of Earth's orbit ).
|
| 40. | The plane of their galactic orbit carries them as far as 463 " 489 away from the galactic plane.
