Which spacecraft visited mercury in the 1970's?
The Mariner 10 probe was the first spacecraft to visit Mercury in the 1970s. It made three flybys of the planet in 1974 and 1975, capturing images and data that provided valuable insights into Mercury's surface and environment.
Is Mercury a solid or a frozen gas?
Mercury, the planet is a solid rocky body.
Mercury, the element is a metal, liquid at room temperature.
How long has mercury been geologically inactive?
Mercury has been geologically inactive for billions of years, with the last significant volcanic activity ceasing around 3.5 to 4 billion years ago. This extended period of inactivity has led to the planet's surface being heavily cratered and preserving ancient geological features.
Mercury rain refers to droplets of liquid mercury falling from the atmosphere. This can occur near industrial areas where mercury emissions are released into the environment, or during volcanic eruptions where mercury is present in the volcanic gases. Mercury rain is a serious environmental concern due to the toxic nature of mercury and its harmful effects on ecosystems and human health.
How many months are in 88 days on mercury?
Answer
2.88 (repeating decimal by doing 88/30.5)
Note: I divided it by 30.5 because that's a month on average it's like saying a mouth Times (x) 2.88 Equals 88 days. Not 7/88 I don't know where you got that.
How does a mercury themometer work?
A Mercury barometer works by expanding and therefore raising the mercury of the barometer, then reading the level up to which the mercury has gone.
Why is Venus hotter than Mercury even though its closer to the sun?
Venus is hotter because it has a thick atmosphere that traps heat, creating a greenhouse effect. This causes Venus to have a much higher surface temperature than Mercury, despite being farther from the Sun.
What planet hols the celestial record for the fastest revolution around the sun?
Mercury holds the record for the fastest revolution around the Sun, completing an orbit in about 88 Earth days. Its close proximity to the Sun results in a faster orbital speed compared to other planets in our solar system.
What is the effect of the planet mercury on humans during its orbit?
Mercury's orbit does not have a direct physical effect on humans. However, astrologically, some believe that Mercury's position in the zodiac can influence communication, travel, and technology, leading to potential challenges or opportunities in these areas.
Is Mars or mercury closer to earth?
Mercury ranges between 0.466 AU and .307 AU - from the Sun. Mars, on the other hand, ranges from 1.655 to 1.381 AU - also, as measured from the Sun. The Earth, of course, averages 1 AU from the Sun, that being the definition of an Astronomical Unit, but it ranges from 1.016 to .983 throughout the course of the year. That mean that Mars is, at its very closest possible approach, .365 AU from the Earth, and Mercury's closest possible approach is .517 AU. On the other hand, Mars could, on rare occasions, range as far as 2.671 AU from Earth, while Mercury never moves farther than 1.482 AU. In actuality, since all three planets are orbiting the sun at different rates, which of the two is closer to Earth at any given moment is a matter of circumstance.
Which planet has a orbital period of 687 days?
Mars has an orbital period of approximately 687 Earth days.
Which planet is about as far from the sun as mercury is?
There is no planet that can be described as "about as far" from the Sun as Mercury. It's the planet closest to the Sun, and the only other planet closer to the Sun than Earth is Venus, which is about twice the distance away from the Sun compared to Mercury. Considering that's a difference of roughly 51,000,000 km (0.32 AU, 1 AU is the average distance from the Earth to the Sun), that's one hell of a long way away. Still, it's closer than any other planet (however, even the Sun is closer to Mercury than Venus).
Why is venus the hottest planet and not mercury?
It's because Venus's atmosphere is mostly composed of carbon dioxide, and there are several layers of clouds many kilometers thick of sulfuric acid. The dense atmosphere traps in heat, producing a green house effect that raises the surface temp about 400 degrees; enough to melt lead.
Mercury, on the other hand, has almost no atmosphere, and therefore no way to hold in heat. While the side of Mercury that faces the sun is hot, the side facing away from the sun is actually quite cold, since heat is not held when the planet rotates.
Is Mercury near or far from the sun?
Mercury is relatively close to the sun, being the closest planet to it in our solar system. Its average distance from the sun is about 36 million miles (58 million kilometers).
What are the smallest to greatest planets?
In terms of size, the planets from smallest to greatest is as follows:
Mercury (smallest), Mars, Venus, Earth, Uranus, Neptune, Saturn and Jupiter (largest). Note that although Neptune has more mass than Uranus, it is smaller in size.
What is mercury's temperature in the day side?
It ranges from 525K to 750K depending on whether it is at perihelion or aphelion.
Which jovian planets has the most moon?
Jupiter has the most moons among the Jovian planets, with a total of 79 known moons to date.
Why there is no life on planet mercury?
Mercury's extreme conditions, such as high temperatures reaching up to 800°F (427°C) during the day and cold temperatures dropping to -290°F (-179°C) at night, make it inhospitable for life as we know it. Additionally, its lack of a substantial atmosphere and constant bombardment by solar radiation and meteoroids would also make it very challenging for any form of life to survive.
What are fish that are both low in mercury AND cholesterol levels can you have them every day?
Fish such as salmon, sardines, and trout are low in both mercury and cholesterol levels, making them safe to consume daily. These types of fish are rich in omega-3 fatty acids, which provide numerous health benefits including supporting heart health and reducing inflammation. Incorporating a variety of fish in your diet can help you meet your nutrient needs while minimizing exposure to mercury.
Is the distance between earth and venus greater than the distance between venus and mercury?
If all three planets are in a straight line, then Earth and Venus are closer (~42 milion km) than Mercury and Venus (~50 million km) but since all three planets have different orbital periods, it is possible for Earth to be on the opposite side of the Sun from Venus and Mercury, in which case they would be closer to each other than Earth was to either of them.
What is the colour of the element mercury?
The same as that of the element silver, the color of which is called "silver" as a color also. A major difference is that mercury is liquid at room temperature and therefore is often more reflective than silver, which is susceptible to tarnishing.
How fast does a 9.8 mercury go?
I'm no expert, but it would have to do with the boat design it is on; the payload; and even which 9.8 (year wise) you had.
I have a 9.8 on a 12' Jon boat and I'd say my top speed on smooth water on average is about 15-20 mph.
How large can a terrestrial planet be and still be habitable?
Practically ,life could exist anywhere. Scientists have discovered extremepholites. A rocky planet has no limit to it's size. Unless it's gravitational pull turns itself into a black hole. the answer is
∞
Do all jovian planets have active volcano?
No, not all jovian planets have active volcanoes. For example, Jupiter and Saturn do not have active volcanoes. However, some of the moons that orbit these planets, such as Io (a moon of Jupiter), do have active volcanoes.
Why does mercury have a shorter year than earth?
Mercury is closer to the Sun than Jupiter, therefore it takes less longer for Mercury to go around the Sun. Likewise Jupiter's year is shorter than Uranus, because Jupiter is closer to the Sun than Uranus.
