21. The inclination of planetary orbits around Vega is likely to be closely aligned to the equatorial plane of this star. 22. :: : : The axis of saturn and its rings are not aligned perpenedicular to the with the equatorial plane . 23. This effect allows the measurement of the angle between the planet's orbital plane and the equatorial plane of the star. 24. For latitudes away from the equator, the ring merely needs to be placed at the correct angle in the equatorial plane . 25. But Terzian said it was not possible to tell whether fliers had emerged along the polar or equatorial planes of nebulae. 26. For the orbit of the Moon around the Earth, the reference plane is taken to be the ecliptic, not the equatorial plane . 27. The Rossiter McLaughlin effect allows the measurement of the angle between the planet's orbital plane and the equatorial plane of the star. 28. Once every 42 years, when Uranus has an equinox and its equatorial plane intersects the Earth, mutual occultations of Uranus's moons become possible. 29. It is 0.72344 Earth radii from the rotation axis and + 0.68811 Earth radii from the equatorial plane , 143.7827 degrees east of Greenwich. 30. Where A is the local sidereal time in degrees, E is the inclination of Earth's equatorial plane to the ecliptic ( Axial tilt ).
