Medicare is a federally funded insurance program for eligible participants 65 or over. Medicare has two parts, Part A (Hospital Insurance) and Part B (Medical Insurance). Medicare does not cover 100% of all costs. CDI recommends purchasing a Medicare Supplement Insurance policy if you have traditional Medicare to help offset your health care costs. If you have questions related to Medicare, contact Medicare or your local Department of Aging (HICAP).
7. Temperatures in our universe range from about 3,500,000,000 Kelvin (a supernova) to about 3 Kelvin (space). Our Sun is a class G yellow star and has an average surface temperature of 5,600 Kelvin.
For the fusion reactions to occur, though, the temperature in the star's core must reach at least three million kelvins. And because core temperature rises with gravitational pressure, the star must have a minimum mass: about 75 times the mass of the planet Jupiter, or about 8 percent of the mass of our sun.
