Size of the Solar System Lab - Astronomy 101 Essay

3. The distance between scale markings on the horizontal scale is 100 km. Comparison of the vertical and horizontal scales indicates that the vertical scale is exaggerated [(10)(100)(1000)] times relative to the horizontal scale.

To convert it to cm, you must times it by 1,000,000, so it is now 198,134,664cm3.

It is easy to flip to the index of an astronomy textbook to discover that, say, the Sun lies 150 million kilometers away from Earth. It is far more difficult (if not impossible), however, to picture this distance in our mind. In this exercise, we will learn to access the often unpalatable distances encountered in astronomy by simply scaling the huge distances to more recognizable, familiar numbers. So long as every distance within the system of interest is scaled by the same

The farther away a star is, the less its parallax. The light year is a unit used to express stellar distance, which is the distance light travels in a year, which is approximately 9.5 trillion kilometers (5.8 trillion miles). The parallax angles are very small. Proxima Centauri is the parallax angle nearest to the star. It is less than one second or arc, which equals 1/3600 of a degree. A human finger is roughly 1 degree wide. The distances to stars are so large that conventional units such as kilometers or astronomical units are often too cumbersome to use.

Venus + Mars: Compare and contrast the evolution of the atmospheres of Mars, Venus, and Earth.

The atmosphere on Venus is composed of mostly Carbon dioxide with small amounts of nitrogen and sulphuric acid. This composition causes a runaway greenhouse gas effect that makes the planet even hotter than Mercury, despite the fact that Mercury is much closer to the sun. The air on Venus is incredibly dense due to the Nitrogen content, which, whilst admittedly is only a small part of the atmospheric composition, is at least four times the amount on Earth. This Atmospheric composition therefore creates a thick layer of

The air is not breathable by humans! Venus's atmosphere also contains traces of extra compounds and elements, such as neon, argon, carbon monoxide, and helium. Atmospheric pressure is over 90 times heavier than that of Earth; sheer crushing power. Clouds of sulfuric acid lay above a layer of carbon dioxide near the crust. These sulfuric clouds block most Muggle attempts to see Venus. On Venus, the climate changes all the time, from an extremely cold temperature to an extremely hot one. The temperature ranges from -364 to 870 degrees Fahrenheit. Venus is the hottest planet in the Solar System, and yet it is Mercury that is the closest planet to the Sun, Venus being second in

Mercury is the closes to the sun and Venus is 2nd close to the sun. Mercury and Venus are inter planets that means they are two of the 4 inter planets. They are not made of gas that is only the outer planets are the only ones that can be made of gas. Venus earth's closest neighbor in the solar system. Venus is the brightest object in the sky after the Sun and the Moon, and sometimes looks like a bright star in the morning or evening sky but I have never seen it before. Mercury is named for the ancient Roman god of trade and profit the roman people believed in many

The Sun is one astronomical unit away so in actuality, it’s 0.00001581 light years away. Sirius looks smaller than the sun because it’s almost 9 light years away, which means it’s 92,919,000 or the astronomical units away. Sirius has a dwarf or twin star next to it, this star is called Sirius B. Sirius B was assumed to exist in 1844 but it wasn’t actually discovered until almost 18 years later!

In many ways Venus is found to be similar to Earth. However their similarities do not extend further than their physical properties, for instance, their atmospheres differ greatly from each other. Venus is said to have atmospheric pressure of 92.1 barometers (Adams, D. Et al., 1994 p.126) which it is evidently 92 times greater than Earth’s that is 1.01 barometers (Adams, D. Et al., 1994 p.126) at sea-level. In spite of this comparison to Earth’s atmospheric pressure, Venus owns an out of the ordinary atmospheric composition.

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

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

Venus' atmosphere is approximately 96.5% carbon dioxide and 3.5% nitrogen, with traces of elements and compounds such as carbon monoxide and helium. Its atmospheric pressure, therefore, is 90 times heavier than that of Earth's. Near the surface of Venus is a thick layer of carbon dioxide, and above that are layers of clouds of sulfuric acid. These clouds of sulfuric acid are highly reflective and reflect more than 90% of the sunlight that hits Venus, and this means that Venus is one of the brightest objects in the sky, behind the Sun and the Moon. These clouds, and Venus' atmosphere have also contributed to a 'runaway greenhouse effect' on Venus, causing its climate to be permanently changed. Theories suggest that Venus once had a climate similar

I have decided since it will take me 43 day to get from Earth to Venus I will write facts about Earth on my way there. Since we are going to the solar system the basic facts about Earth are necessary. Earth is third planet from the Sun, and the fifth largest in our Solar System. 71% of Earth’s surface is covered in water, and the remaining 29% is

Some of the scientific data that follows was taken out of Cattermole's book. The mean distance from the sun is 108.20 Km.
