This means that as a planet gets closer to its parent star, it speeds up; as the planet gets farther away, it slows back down. Kepler's third law: An object's orbital period squared is equal to the cube of its
NASA researchers have found that at 1 astronomical unit (AU), which is the distance from the sun to Earth, equal to 93 million miles (150 million km), sunlight can produce about 1.4 kilowatts (kw) of power. If you take 1.4 kw and divide it by the speed of light, you would find ...
A rule of thumb is that the transfer to Mars takes around as long as the human period of gestation, approximately 9 months. But that really is no more than an approximate value; you still have to do all the math to find out what applies to a specific date. Why are journey times a ...
TheLeo constellationcan be seen at latitudes between 90 and minus 65 degrees. To find Leo, first look for the bright star Regulus and then trace the distinctive backward question mark known as "The sickle" which represents the lion's mane. Don't look directly at Leo to find meteors, as ...
2.1 The anomalsitic period and the mean motion One of the six Keplerian orbital elements in terms of which it is possible to parameterize the orbital motion of a planet is the mean anomaly M. It is defined as M≡ n(t − T 0 ) where n is the mean motion and T 0 is the tim...

Novelist Angela Hunt refers to this as The Bleakest Moment. It’s where even you wonder how you’re going to write your way out of this. The once-reprobate lover who has become a changed man and a loving fiance suddenly falls off the wagon the night before the wedding. ...
Fungi have been companions of mankind for millennia. Mushrooms inspired our eating culture, and yeasts and filamentous fungi were developed into highly efficient cell factories during the last 100 years to produce many products utilized in different indu
third shell of an atom, which consists of nine suborbitals, can hold a maximum of 18 electrons, according toFlorida State University's Department of Chemistry and Biochemistry. That means selenium has 2, 8, 18 and 6 electrons in its first, second, third and fourth atomic orbital, ...
