Planet Mercury
The planet closest to the sun and the smallest one in our solar system.
1,826 Questions
Mercury is desert-like because it has a very thin atmosphere that is unable to retain heat or support weather patterns. The lack of atmosphere also means that there is no protection from solar radiation or meteorite impacts, resulting in a barren and inhospitable landscape similar to a desert on Earth.
Why is mercury not visible from earth?
It is visible, but not obviously as a planet.
It is millions of miles away, and appears as a very bright star near the horizon, shortly before dawn or shortly after sunset. For some of the year, it is invisible because it appears too close to the Sun.
What are the planets like mercury venus and mars?
Mercury is the closest planet to the sun and has extreme temperature variations, with scorching hot days and freezing cold nights. Venus is the hottest planet in our solar system due to its thick atmosphere of carbon dioxide, which traps heat. Mars is known as the "Red Planet" due to its iron-rich soil, and it has a thin atmosphere with features like volcanoes, canyons, and polar ice caps.
Why does mercury have a strong magnetic field?
Mercury's strong magnetic field is believed to be generated by a liquid iron core that undergoes slow rotation, creating a dynamo effect. This process generates a magnetic field that is proportionally stronger relative to the planet's size compared to other planets in the solar system.
When was it discovered that mercury was poisons?
Mercury was found as a residue from gold and people started drinking it believing it was the "Elixir of Life" around the 20th century. Well, once people died they learned it was poisonous and conducted research as to why. Though I won't go into great detail about this needless to say mercury should never under any circumstances be drunk or sniffed. Though, I know noone was planning to do so... Hope this helped... If not... TOO BAD! JKJKJK
What is the radial acceleration of the planet mercury?
I guess you mean the centripetal acceleration in its orbit around the Sun. That's not something that will usually be found in references such as the Wikipedia, but you can calculate it in several ways.
1) Use the law of gravitation to calculate the force between an object of mass 1 kg. at Mercury's distance from the Sun, and the Sun. Any other mass will do as well, but after calculating the force, you need to calculate the acceleration, so the mass of Mercury (or another object at the same distance) cancels in the calculation.
2) Look up Mercury's orbital data. Assuming a circular orbit, calculate the centripetal acceleration as v2/r.
Was an Xbox 720 really found on Mercury?
No. That was an internet hoax.
No human has ever set foot on planet Mercury. Planet Mercury is 427 Degrees Celsius. A human, or any human-made object such as an Xbox console, would burn up and turn into ashes within seconds.
How many star does mercury have?
None, It is in the solar system which has 1 star (sun), It orbits around the sun. And is the closest to the sun. If you are talking about moons Mercury has NO moons.
Hope that helped... your question didn't really make sense. :P
When did space probes depart to mercury?
There has never been a NASA exploration mission to the surface of Mercury, but the MESSENGER spacecraft has been in orbit and taking pictures of the planet since 2008.
Before that, in 1974, the "Mariner 10" probe took photos of Mercury.
How long does Mercury take to rotate 360 degrees?
The Mercury Year (time to revolve around the Sun) is 3/2 the Mercury day (time to revolve once on its own axis relative to the distant stars)
Mercury orbital period about 87,97 Earth days
Sidereal day (relative to the stars) 58,7 earth days.
Why isn't the surface of the earth cratered like the moon or like mercury?
Earth's surface is not as heavily cratered as the moon or Mercury because Earth has active geological processes such as weathering, erosion, and plate tectonics that continuously reshape its surface. These processes help to erase or cover up impact craters over time, maintaining Earth's relatively smoother appearance compared to the heavily cratered surfaces of the moon and Mercury.
What planets period of rotation is 590 minutes?
Jupiter, the largest planet in the solar sytem.

How does crash gets his nickname?
Crash Bandicoot gets his nickname "Crash" from his tendency to crash through obstacles and enemies in his adventures. His reckless and adventurous nature often leads him to charging headfirst into situations, earning him the name "Crash."
Why are there no seasons on mercury and venus?
The reason that seasons occur is the orientation of the planet to the Sun, caused by a tilt in its rotation compared to its orbital plane. The Earth's axial tilt is about 23.5° which provides a noticeable variation in temperatures globally depending on the Earth's position in its orbit.
Mercury and Venus are quite different, but neither has much inclination to its rotation, about 2° to 3°, so even if they were Earth-like planets, they would have very little seasonal variation.
However, there are larger factors:
- Mercury's rotation is very slow compared to its year, and Venus has almost no rotation at all.
- Mercury has no atmosphere and experiences vast swings in surface temperature (88 Earth days of blistering heat followed by 88 Earth days of incredible cold).
- Venus is just the opposite: its dense atmosphere does not allow sunlight to reach the surface, but is a year-round pressure cooker, giving the whole planet a temperature around 860°F.
Under these circumstances, a minor change in the angle of sunlight would have negligible effects on the surface conditions.
How long is a year in the planet mercury not in earth years?
A year on Mercury, in terms of the time it takes for the planet to complete one orbit around the Sun, is approximately 88 Earth days. This is due to Mercury's closer proximity to the Sun and its faster elliptical orbit.
How long is one day in rotation time on Mercury?
All planets have a different length of "day." Depending on whether or not you consider a day to be one full rotation. The lengths of days are as follows:
Mercury: 175.94 Earth Days.
Venus: 116.75 Earth Days.
Earth: 24 Hours
Mars: 24 Hours, 39 minutes, and 35.24 seconds
Jupiter: 9 Hours, 59 minutes, 33 seconds
Saturn: 10 hours, 32 minutes, 35 seconds
Uranus: 17 Hours, 14.4 minutes
Neptune: 16 Hours, 6.6 minutes
Pluto: 6 days, 9 Hours, and 17 minutes.
How long to travel from the sun to Mercury?
Mercury is about 57,500,000 kilometers (36,000,000 miles (36 million miles)) from the Sun, Earth is about 152,000,000 (93,000,000 miles (93 million miles)) - a little less than 3x farther away. Since it takes about 9 minutes for light to get to Earth from the Sun, it stands to reason it would take about 3 minutes to get to Mercury from the Sun.
Light to Earth
152,000,000,km/300,000km/s ~ 506 secs, 506secs x 1 min/60 secs ~ 8.5 mins
(93,000,000 miles/ 186,292 miles per second ~ 499 seconds, 499 seconds x 1 min/60 seconds ~ 8.3 mins, )
Light to Mercury
57,500,000 kilometers/300,000km/sec ~ 192 sec, 192 sec x 1 min/60 secs ~3.2 mins
(36,000,000 miles/186,292miles/sec ~ 193 sec, 193 sec x 1 min/60 secs ~ 3.2 mins)
What is Mercurys' radius with regard to the earth?
Earths mean diameter is 12756km at the equator, Mercury's diameter is 4879km. Mercury diameter is 0.3824 of Earths (if Earth is 1), or put another way, Earth diameter is 2.6 times bigger than that of Mercury.
How long is one year on mercury comparison to earth years period of revolution?
If memory serves, Mercury revolves around the sun once every 88 days, so a year on Mercury would be just shy of three months on earth.
Which planets are closest in orbital speed?
The orbital speeds are higher when closer to the sun, but slower and more similar as you move out. The two that are closest in speed are Uranus and Neptune. Uranus at 6.8352 km/sec and Neptune at 5.4778 km/sec.
Is there a rhyme to planets in smallest to largest?
Yes, there is a common rhyme to remember the order of the planets in our solar system from smallest to largest: "My Very Educated Mother Just Served Us Noodles." This corresponds to Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
Who was the first man who discover planet mercury?
The planet Mercury has been known since ancient times, so it is not possible to attribute its discovery to a single individual. However, it is likely that ancient civilizations such as the Sumerians, Babylonians, and Greeks observed and recorded the existence of Mercury in the night sky.
What factors make life as we know it impossible on Mercury?
The planet is rock. You life cannot exist inside rock (to be sure in the cracks and fissures of rocks on Earth there is some life... but, see below).
Life probably does not exist on Mercury because of the lack of atmosphere and the proximity to the Sun makes for extremes of temperature that no known life form could withstand.
What planet aside from the earth is safe to live?
Earth is the only place to live! As of 2009, mankind has not created any living spaces off planet, so you are stuck here! There are areas which are safer than others, and there are some areas that are dangerous. You should learn about any area before you travel through or try to live in it.
NO, we humans are killing it. We should recycle more. We should stop using river water to drink and ride our bikes more often.What type of planet has a solid rocky crust?
A terrestrial planet has a solid rocky crust. Terrestrial planets are typically smaller and denser than gas giants, with a composition of rock and metal. Examples include Earth, Mars, Venus, and Mercury.
