be more than 90 times heavier than on planet Earth. Although Venus is not the closest

Mercury, the closest planet to the Sun, is a rocky planet. The heavily cratered planet suggests that meteors or comets were frequent many, many years ago. Mercury's boulder littered surface and pale gray appearance slightly resembles Earth's moon. Like Mars, Mercury is covered in pulverized dust. What Mercury lacks in this, is weather. Muggle probes bring images to us that show no signs of wind, dust storms, or clouds. No rivers have been found on Mercury. Lack of clouds and rivers, (and oceans) suggests that there is no water on the closest planet to the Sun, Mercury. One of Mercury's most famous craters is Caloris basin, which is 1550 km in diameter. Another of Mercury's most famous craters is called Rachmaninoff. Rachmaninoff is 306 km in diameter. These two very large craters were created by astroids impacting the planet in Mercury's early history.

For my vacation, my family has chosen to go to Venus. This our first year traveling outside of earth so we chose a planet close. Venus is covered with a thick layer of sulfuric acid which will be a blast to land into but on the inside Venus is solid. Venus shines super bright and has orangish yellow tint. The overall look of Venus is dreary and the gas covers the area with a goldish hue and everything looks like gunmetal. Venus is VERY hot, it temperature reaches to about 870 degrees Fahrenheit! On top of the scorching heat the Atmospheric pressure is bone crushing and highly dense.Venus is about 0.72 light years away from the Sun and blank light years from Earth. Venus is very much like earth and not very much like earth. Venus is about the same size as earth

However, it turns out that Mars is much more hospitable to life on its surface than Venus. Due to its runaway greenhouse effect, our sister planet is the hottest planet in our solar system. Temperatures on the Venusian surface can reach smoldering temperatures of nearly 900 degrees Fahrenheit, hot

To compare, all three planets have secondary atmospheres that were produced by volcanoes. To contrast, Venus is too close to the Sun, and was too warm for liquid water to form and without liquid water; the CO2 could not settle out of the atmosphere and dissolve into the oceans. This caused Venus to suffer from runaway greenhouse effect and became hot with an extremely dense and vastly insulated atmosphere. Along with this, UV sunlight destroyed the H2O in the atmosphere. On the other hand, Earth had enough distance from the Sun for liquid water to form and precipitate out into the ocean while the CO2 in the atmosphere dissolved into the oceans and was removed from the atmosphere. The trace amounts of H2O and CO2 in the atmosphere create an insulating layer which is enough to keep the Earth at a mild temperature. Out of the three planets, Mars is the farthest from the Sun. It is possible that Mars had liquid water earlier in its history. The CO2 dissolved into water; however, Mars has less mass than Venus or the Earth. Because of Mars’ smaller mass, it has less tectonic activity and Volcanism stopped early in its formation. This did not allow the atmosphere to be renewed from CO2 or H2O

Atmosphere can be defined as a gaseous compound layer surrounding a large body mass suspended by means of gravity and centrifugal force caused by rotation [1]. Atmospheres of planets have not always been the same, its evolution comprised of complex development across million years of geologic time affected by various changes of variables inside and outside its planet [2]. Of the interest of this essay is the atmospheric evolution of a rocky planet. Rocky planet is a terrestrial body consists mainly of silicate or metal [3]. Some known rocky planets with substantial atmosphere such as Venus, Mars and Earth has a very different composition of atmospheric gas [4]. These planets experienced very

It is believed that only 55% of Mercury has been mapped, however, that 55% has yielded a number of interesting finds, there are three significant geological features on Mercury, these are: smooth plains, intercrater plains and rugged highlands. The smooth plains resemble Lunar Maria, that is, large dark basaltic plains formed by ancient volcanic eruption, found on the Earth’s moon. The Intercrater Plains are impact craters, pocked with a number of smaller craters, which cover 70% of the examined surface. These craters are particularly deep, due to the planets lack of an atmosphere to slow the bodies before impact. The rugged highlands resemble mountainous regions of the Earth; however, there is no evidence of tectonic motions to have caused them. Mercury is made up of predominately iron, its crust is only 500-600km thick and there is evidence of volcanic activity, although it is believed that the planet has been geologically dormant for billions of years.

At night planets can reach a freezing negative two hundred seventy-five, since it doesn’t have much of a true atmosphere to hold any heat. In its upper atmosphere it has some water vapor but the humidity is not measurable in any results. There is no precipitation due to the water vapor staying in the planet’s upper atmosphere. Mercury does not have any conventional wind due to the small amount of pressure that it generates. Since Mercury has craters, they are filled with ice which also causes the temperature to drop during the night.

You are now ready to explore every planet in our solar system. You will learn tons of cool facts about each planet. This will also teach you about where the names of our planets came from and what the planet is known for. Mercury and its speed.

One of these terrestrial planets, Mercury is the topic of the next section. Mercury, one of the smallest planets, has a surface similar to that of a moon because it is cratered with some smoother areas. However, it is distinct from the moon in that the plains are the same color as the cratered areas. Mercury

Before we arrive to Venus let me inform you that we aren’t actually landing on Venus or any of the planets . Venus can literally kill you in 10 seconds or less. Venus is the second closest planet to the Sun. Which makes Venus 464 oc (867 oF), and it's the hottest planet in our Solar System. The reason why Venus is the hottest planet and not Mercury is because Venus's atmosphere is mostly made up of carbon dioxide. Which is a prevalent greenhouse gas. In my next entry I will get into what a greenhouse effect is.

Scientists examined the Venusian atmosphere and found out that above the clouds the temperature is about 13oC, in contrast, at the surface of Venus the temperature gets as high as 465oC. It is believed that the principle cause of the extreme surface temperature is the consequence abundant carbon dioxide (CO2) in the atmosphere. Scientists concluded that Venusian atmosphere undergoes greenhouse effect. In essence, the heat delivered from the Sun enter the atmosphere and is radiated out, then again, it does not leave the atmosphere due to its heavy clouds that impede it from such. For this reason, Venus’ surface temperature is higher than that on Mercury – higher than any other planet! – leaving no chance of life.

Venus is the 2nd planet from the Sun. Venus' reflective nature and close proximity to Earth are major factors in it's being one of the brightest objects in the sky after the Sun and Earth's moon. It is often referred to as

The atmosphere on Mars is a thin layer composed mostly of carbon dioxide. Nitrogen, argon and small traces of oxygen and water vapor are also present. The atmospheric pressure on Mars depends on how high or low the land is elevated. The atmosphere on Venus is composed mainly of carbon dioxide with minor amounts of nitrogen and trace amounts of nitrogen, helium, neon, and argon. Venus is much denser than earth and thick with clouds of carbon dioxide. The clouds create a greenhouse effect which makes Venus the hottest planet in the solar system.

The atmosphere of Venus made up of 98% carbon dioxide and 2% Nitrogen. This atmosphere also has the presence of helium, neon and argon. This is yet another thing which makes Venus different from Earth.
