date - Essay ExampleBy looking at the Earths cooking stove from the above its sector appears to be much more elliptical.The next step involved measuring the radical velocity the genius Arcturus in the solar neighborhood. The star Arcturus is relatively close to the Sun hence its temperature is slightly different from that of the sun. Zooming into the little(a) regions of the spectrum of individual stars, similar absorption lines are observed. The little offset in wavelength is as a allow for of movement of Arcturus.Since we have obtained the value of the earths velocity as 129.74 km/sec, and the period of its orbit is known to be one year, we can calculate earths radius (in astronomical units) victimization the formula5. The apparent color of the Arcturus changes with the radical velocity. If the object is close to the observer only a virtuoso edge of shifting to the other but if the object is far away they will appear as a small dot of light. Incase the observer is moving qui ckly, the interference of wavelengths will result in spreading of individual lines, a condition known as rotational broadening (Richmond
