Studies show drinking coffee prior to a workout reduces muscles soreness and fatigue by nearly half. Assuming no medical contraindications to the use of caffeine, I recommend two cups of coffee prior to workout, says Ann Kulze, M.D., author of the best-selling Eat Right for Life series.
Earth 's orbital plane is known as the ecliptic plane, and Earth's tilt is known to astronomers as the obliquity of the ecliptic, being the angle between the ecliptic and the celestial equator on the celestial sphere. It is denoted by the Greek letter Îµ.t an obliquity of zero, these lines point in the same direction i.e. the rotational axis is perpendicular to the orbital plane. Axial tilt differs from inclination. Because the planet Venus has an axial tilt of 177Â° its rotation can be considered retrograde, opposite that of most of the other planets.
This is what is known axial tilt, where a planetâs vertical axis is tilted a certain degree towards the ecliptic of the object it orbits (in this case, the Sun). Such a tilt results in there being a difference in how much sunlight reaches a given point on the surface during the course of a year. In the case of Earth, the axis is tilted towards the ecliptic of the Sun at approximately 23.44Â° (or 23.439281Â° to be exact). 1  Earthâs axis points north to Polaris, the northern hemisphereâs North Star, and south to dim Sigma Octantis. 2  Artistâs rendition of the Earthâs rotation and the precession of the Equinoxes.
