Answer 2

Mercury

• Mercury is the nearest planet to the sun and the smallest, barely slightly bigger than Earth's moon, zipping around the sun in only 88 days.
• Mercury's day and night temperatures are dramatically different because of its near proximity to the sun (approximately two-fifths the distance between Earth and the sun).
• Daytime temperatures can soar to 840 degrees Fahrenheit (450 degrees Celsius), which is hot enough to melt lead. Temperatures at night plummet to - 290 degrees Fahrenheit (minus 180 C).

• Mercury, like the moon, has a very thin atmosphere of oxygen, sodium, hydrogen, helium, and potassium that can't break up incoming meteorites, hence its surface is littered with craters.
• NASA's MESSENGER spacecraft made remarkable new findings that defied scientists' expectations during the course of its four-year mission.

Venus

• Venus, the planet closest to the sun, is the same size as Earth.
• Underneath its atmosphere, radar pictures reveal a variety of mountains and volcanoes on its surface.
• Aside from that, the two worlds are diametrically opposed. Venus is an extreme example of the greenhouse effect due to its thick, poisonous atmosphere, which is made up of sulfuric acid clouds.
• It's sweltering, hotter than Mercury.
• On Venus's surface, the average temperature is 900 F. (465 C). The surface pressure would crush and kill you at 92 bar.
• Venus also rotates slowly from east to west, which is the polar opposite of most other planets.
• Venus was thought to be two separate objects by the Greeks, one visible in the morning and the other in the evening sky.
• Venus has sparked several UFO sightings since it is typically brighter than any other object in the sky.

Earth

• Earth, the third planet from the sun, is a water world, with oceans covering two-thirds of its surface.
• It's the only place on the planet where life is known to exist. The nitrogen and oxygen content of the Earth's atmosphere is high.
• At the equator, the Earth's surface spins at 1,532 feet per second (467 meters per second), slightly faster than 1,000 miles per hour (1,600 kilometers per hour).
• At almost 18 miles per second, the planet zips around the sun (29 km per second).
