Planet Mercury

Parent Category: The Solar System
The planet closest to the sun and the smallest one in our solar system.
Mercury's atmosphere contains small amounts of hydrogen,helium, and oxygen. It also has even tinier amounts of sodium,potassium, calcium, and magnesium. Some of the gas particles comefrom the solar wind. Others are made by radioactive decay or whenmicrometeorites smash into the surface.
To revolve around the sun, it takes 88 days. To rotate on its ownaxis, it takes 58.6 days. One rotation takes 175.97 Earth days
This tells you that, because Mercury is very cratered, it must haveno protection against the asteroids coming in. So, it is basicallytelling you that Mercury has a very thin atmosphere
no, because a human would suffocate and die of intense heat.
Mercury contains a solid, rocky landscape composed of numerous volcanoes, however it is so close to the Sun that you would most likely burn up before you reached the surface.
Mercury is definitely not perfectly round. All of our photos ofMercury show that it's covered in craters which cause ridges toform all over the planet. This means that it's not perfectly round.
No, one Mercury day is equal to 58.6 Earth days
According to our science books, the temperature on Mercury ranges between -173 and 427degrees Celsius. Take that for what it's worth lol
The planet Mercury was named after an ancient god of Rome. The nameoriginally came from the Greek god who was known for his speed.
how does the planet mercury's spins?
The temperature of Mercury can reach up to 450 degrees C (840 degrees F) during the day. At night, the temperate can drop down to -170 degrees C (-275 degrees F).
At what distance from the Sun would a planet's orbital period be 3 million years?
mars and jupiter \n\nNot Jupiter, Venus is closer than Jupiter is. Mars is correct though.
No, Charon is not larger than Mercury. Its smaller than Pluto, and Pluto is smaller than Mercury.
No, but we have a satellite in orbit called Messenger and the Mariner made an early flyby in the 1970s and went into orbit around the Sun where it could continue to observe Mercury.
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and maybe Pluto.... they aren't sure if it is a planet.
Mercury, Venus, Earth and Mars.
yes. It will be destroyed by the sun because the sun is always getting bigger until it explodes in 5.4 billion years.
No it doesnt! the reason behind this is that Murcury has no atmosphere so it is unable to hold any sort of gas.
The planets in order from the sun are: Mercury. Venus. Earth. Mars. Jupiter. Saturn. Uranus. Neptune.
Mercury's volume = 0.056 x Earths (6.08x10 10 km 3 ) Venus' volume = 0.857 x Earths (9.38x10 11 km 3 ) (Earth) volume = 1 x Earths (1.08x10 12 km 3 ) Mars' volume = 0.151 x Earths (1.63x10 11 km 3 ) Jupiter's volume = 1321.3 x Earths (1.43x10 15 km 3 ) Saturn's volume = 763.59 x...
The planet Mercury is gray-brown. It has a very thin atmospherethat does not contribute to its coloring, and therefore all that isseen is its surface.
369 000 100 decktomiles estimated. SUN MERCURY 369 000 100 decktomiles (estimated)
Johann Schröter made observations of surface features, claiming to have observed 20 km high mountains
the diameter of mercury = 4 879.4 kilometers
U can't it's only in the morning at 2:00,2:45 that's the only time u can see it lol
Venus has an atmosphere that is mostly carbon dioxide, which allows heat to enter, but not to leave. This is known as the greenhouse effect. Mercury is too small to have an atmosphere, and thus no greenhouse effect. Even though Mercury is much closer to the Sun, most of the heat radiates back out...
It takes Mercury just over 58 days to rotate on it's axis and 88 days to orbit the Sun
During the sunset or the sunrise for a brief amount of time.
The diameter od mercurys core is 3,600 km, 2,235 miles.
LOL -- We'll have to dance slowly to answer this question.
No it will not at all be easy.As you know mercury is the first planet in terms of distance from sun.Moreover It is an exceptionally dense planet due to the large relative size of its core. Surface temperatures range from about 90 to 700 K (−183 °C to 427 °C, −297 °F to 801 °F),...
no it does not
There are two spacecraft who tried to land on the planet mercury.The first of two spacecraft to visit the planet was Mariner 10 , which mapped only about 45% of the planet's surface from 1974 to 1975. The second is the MESSENGER spacecraft , which mapped another 30% during its flyby of January...
Mariner 10 found out that Mercury looked like the Moon. Also that Mercury is very hot during the day, but very cold at night!
Mercury has a rotation period of 58.646 days.
The mass and diameter of the planet Mars is less that of Earth sothere are changes to how the gravity effects you. This would causea normally 150 pound person to only weigh 56 pounds on Mars.
There is alot less gravity then on earth.
Because Mercury lack of atmosphere
The atomic symbol for the element Mercury is Hg. This comes fromthe Latin word hydrargyrum, which means liquid silver.
mercury was named after the roman god of commerce and thievery, because it quickly appears and dissapears from our view.
Yes because Mercury has a very thin atmosphere, and the atmosphereis what protects the planet from impacts on the surface.
It takes 243 Earth days to make a full rotation or 1 day.
It is cold because of the lack of atmosphere. The sunlight cannot reach the dark side of Mercury, and there is not enough of an atmosphere to hold it the heat.
Why is it cooler to sit behind an umbrella on the beach one a Sunny day as apposed to sitting in the sun light? The same reason the back side of Mercury is cooler, it's not in the direct radiant energy of the sun so it's cooler.
Mercury: In Roman mythology the herald and messenger of the gods, god of commerce ( trade), eloquence, (speaking poshly) travellers, merchants and thieves.
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto hope that answers your question
mercury is the first planet in the solar system with the shortest year and the longest day. the temperatures here are incredibly extreme and so it cannot support life. moreover, it has a very thin atmosphere which allows radiations, both harmful and useful, to pass through it. if any creature can...
Mercury takes 59 Earth days to rotate once and 88 Earth days to complete an orbit of the Sun. This means that a solar day on Mercury lasts about 176 Earth days, which is about twice as long as Mercury's orbital period. As a result a Mercury year is about 0.5 Mercury days long and one Mercury day...
We don't know anything about what the bob is hung with. Is it a bamboo pole ? A steel rod ? A chain or 1/4" aluminum cable ? Is it a thin massless thread ? It makes a difference, because the arc-period of the whole assembly depends on the length between its center of mass and the pivot. ...
Uranus was discovered by Sir William Herschel in 1781. Herschel was probably the most famous astronemer of the 18th century. In addition to discovering the planet Uranus, he also observed and cataloged over 800 double stars and 2,500 nebulae. He was the first astronomer to correctly describe the...
A mercury day (sidereal rotation period) is 58.646 earth days = 1407.5 hours.
the fuel reset switch is located in the truck of the car, drivers side (left side) behind the trunk side cover, you have to remove the carpeted cover to access the relay reset (theres a red button on top)
90520 days * (1 year/365days) = 248 years 90520 days * (1 year/365.25days) = about 247.8 years It's about 248 years whether you take leap years into consideration or not.
mercury because it is the closest to the sun
The revolution of Mercury is 88 days, and its rotaion is about 58.6 days.
It takes 87.97 earth days to orbit around the sun.
No, the largest planet is Jupiter, which is one of the outer planets.
Venus comes after Mercury.
78 hours 87 earth days
Mercury is an element, so it can only be broken down further into subatomic particles (proton, electron and neutron).
\nThe surface area of the planet Mercury is about 74,800,000 km 2 or about 10% the surface area of the Earth..
i need help with one too haha! i don't know what I should put though. I have seen some and one said like "Mercury, so hot u could get a tan!" or something idk. Do u have one or anyone else? maybe you could put, "Mercury, Fry eggs on the floor!!" that's pretty old XD
It's because Venus has a thick carbon dioxide atmospherethat trapsthe Sun's heat. It's the "greenhouse effect".
There are 449680 earth days in one Mercury year.. From 3limes
Caloris Basin I think is the deepest and the youngest too.
There isn't a whole lot going on in the atmosphere of Mercury. It was unclear if Mercury actually had an atmosphere or not until '74 when Mariner 10 discovered an exosphere (an extremely thin atmosphere) around Mercury. Some of the elements that are in this exosphere are hydrogen, helium, oxygen,...
Mercury, Venus, Earth, Mars. In that order.
It was reclassified as a dwarf planet.
Year: 88 Earth days. Rotation period (sidereal day): 58.6 Earth days. Solar day: 176 Earth days.
Because Venus has a very thick atmosphere of carbon dioxide that retains the heat due to the greenhouse effect.
The Mariner 10 and the MESSENGER
Some areas of Mercury don't see the Sun, and it can be about 300 degrees below zero Fahrenheit. There is even believed to be ice on Mercury. However, mostly it is very hot, over 800 degrees Fahrenheit.
