The Earth revolves around the sun at a speed of about 67,100 miles per hour. One whole orbit or revolution around the sun takes approximately 365.25 days, which comes out to a year. The extra 0.25 day is accounted in the extra day on leap years every 4 years. The Earth’s axis is ...
Until recently however, these two communities were mostly independent from one another and the potential resolving power of integrating their efforts in deep time has been largely underutilized.CRAMER, Bradley D
Semiconductors are in greater demand than ever: The Fourth Industrial Revolution (4IR), which is currently transforming manufacturing, production, and, more generally, global business, is characterized by smart computers and connected devices. Smart means connected, and connected means semiconductors. ...
Because the orientation of Earth’s tilt has a slight wobble (a motion called precession), the time from one March equinox to the next is a fraction shorter than Earth’s orbital period around the Sun. The time for one orbital revolution around the Sun is called a sidereal year—this is...

When a planet gets big enough, when it acquires enough mass, it migrates inwards towards the star. Understanding this phenomenon was a real revolution.当一颗行星变得足够大，当它获得足够的质量时，它会向恒星内部迁移。理解这一现象是一场真正的革命。Planetary migration explains why the majority of ...
The path of the earth around the sun is an elliptical shaped orbit. But it should be noted that the exact path of the planet changes slightly over time. These changes in orbit can affect certain natural events on the planet, like weather and climate.

What is a time period?Question:What is a time period?Period:Every body whose movement is periodic has a time that is known as a period. The period is the time it takes for the body to make a complete turn, that is, to return to the point where it initially started. In the movement...
Of the moon, we always see a hemisphere and a little more because its rotation is synchronous and blocked by the tide. This means that one lunar rotation on its axis corresponds to the time of revolution around Earth, equal to 29.5 days. On a daily basis, the moon appears to move eastw...
