Ancillary care refers to the wide range of healthcare services provided to support the work of a primary physician. These services can be classified into three categories: diagnostic, therapeutic, and custodial. Diagnostic services include laboratory tests, radiology, genetic testing, diagnostic imaging, and more.
Mars has an axial tilt of 25.19Â°, quite close to the value of 23.44Â° for Earth, and thus Mars has seasons of spring, summer, autumn, winter as Earth does. As on Earth, the southern and northern hemispheres have summer and winter at opposing times.
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. Earth currently has an axial tilt of about 23.4Â°. This value remains about the same relative to a stationary orbital plane throughout the cycles of axial precession. But the ecliptic (i.e., Earth's orbit) moves due to planetary perturbations, and the obliquity of the ecliptic is not a fixed quantity.
