Planet mercury show phases like moon. This is due to the fact that the mercury lies in the orbit of the earth. So, as mercury revolves around the sun, its sunlit surface is visible in varying amounts from the earth this produces phases of mercury. Many features of the mercury and Earth’s moon are as follows:

So, as mercury revolves around the sun, its sunlit surface is visible in varying amounts from the earth this produces phases of mercury. Many features of the mercury and Earth’s moon are as follows:

1] Mercury and moon both are nearly of the same size and mass.

2] Mercury and moon both have no atmosphere.

3] Mercury and moon both have rocky surface covered with craters.

Mercury and moon both show phases when viewed from the earth.

Venus is the second planet from the earth Venus is slightly smaller than the earth.Venus is a rocky planet. The planet Venus has a dense atmosphere which consists almost entirely of carbon dioxide gas.The cloudy atmosphere of Venus is an excellent reflector of sun light. The planet Venus is the brightest object in the night sky(except the moon).Being quite near to the sun , the planet Venus is very hot .The planet Venus also gets heated excessively by the trapping of the sun’s heat rays by carbon dioxide gas present in its atmosphere which is also called green house effect The maximum temperature on the planet is 480°c.

Slide 13

The planet Venus can be seen as a morning star in the eastern sky or as a evening star in the western sky The venues shows phases like moon. This is due to the fact that the Venus lies inside the earth’s orbit. So, as Venus revolves around the sun,its sun-lit surface is presented to the Earth in varying amounts. This produces the phases of the Venus.Life cannot exist on the planet Venus because it is extremely hot,it has no water and there is no sufficient oxygen in its atmosphere. Mercury and Venus are only two planets which have no satellites or moons revolving around the sun.
