How far away does Mercury get from our sun?
43 million miles When it is closest to the sun, it is only 29 million miles (47 million km), but at its farthest, the distance to Mercury is 43 million miles (70 million km).
How far is Mercury from the Sun and Earth?
Mercury is the first planet from Sun and Earth is the third planet from the Sun. Mercury is an average distance of 48 million miles (77 million km) from Earth. The precise distance between the two planets depends on where they are in their respective orbits.
How many light years would it take to reach Mercury?
In light years, that number would be 0.000006123880620837039 light years away. It's much easier to say that it is about 3.3 light minutes away, meaning it would take about 3.3 minutes for light to travel between Mercury and the sun.
How long would it take to get to Mercury?
The fastest spacecraft ever launched from Earth is NASA's New Horizons mission, currently on its way to visit Pluto and the outer Solar System. New Horizons is traveling at about 80,000 kilometers per hour. It would take about 40 days to get from the Earth to Mercury when they're closest.
Can we land on Mercury?
Could humans land on Mercury's surface? In spite of being so close to the Sun, and wild swings in extreme temperatures, humans could technically walk on the planet's surface. Mercury's slow rotation means it takes 59 Earth days for it to turn around once.

What is the hottest planet?
Venus It has a strong greenhouse effect, similar to the one we experience on Earth. Because of this, Venus is the hottest planet in the solar system.
Will we ever land on Mercury?
It's Time to Find Out, Scientists Say. Mercury has been devoid of spacecraft companions since NASA's Messenger mission ended in 2015, and while the next mission bound for the innermost planet launches later this year, it won't arrive until 2025.
How long will it take to go to Pluto?
With a maximum velocity of 590 miles per hour, the trip to Pluto will only take about 680 years. Which really puts things into perspective when considering just how wild it is that we have a spacecraft about to reach Destination Pluto.
Does diamonds rain on Jupiter?
But in the dense atmospheres of planets like Jupiter and Saturn, whose massive size generates enormous amounts of gravity, crazy amounts of pressure and heat can squeeze carbon in mid-air — and make it rain diamonds.
What planets have we not explored?
Out of the five planets known since ancient times as the 'wandering stars', Mercury is the one least explored. Unlike Venus, Mars, Jupiter and Saturn, Mercury is notoriously difficult to observe from Earth.
How cold does Mercury get?
Mercury's surface temperatures are both extremely hot and cold. Because the planet is so close to the Sun, day temperatures can reach highs of 800°F (430°C). Without an atmosphere to retain that heat at night, temperatures can dip as low as -290°F (-180°C).
What made Mercury not a livable planet?
Mercury's surface temperature reaches a scorching 430 degrees Celsius (800 degrees Fahrenheit) during the daytime, and in the absence of an atmosphere, it plummets to -180 degrees Celsius (-290 F) at night. So, its surface environments have rightfully been out of scientific consideration as a possible host of life.
What planet is coldest?
Uranus The coldest planet in our solar system on record goes to Uranus which is closer to the Sun and 'only' about 20 times further away from the Sun than the Earth is. The lowest temperature recorded there was minus 224 degrees Celsius.
What is Earth’s twin planet?
Venus Venus is often called "Earth's twin" because they're similar in size and structure, but Venus has extreme surface heat and a dense, toxic atmosphere.
Why can’t astronauts go to Venus?
Venus is not easy to visit. Its carbon-dioxide-rich atmosphere is 90 times as dense as ours, and surface temperatures average 800 degrees Fahrenheit. Its surface pressure is intense enough to crush some submarines. But that hasn't stopped human space programs from trying.
How long would it take to fly to Mars?
The trip to Mars will take about seven months and about 300 million miles (480 million kilometers). During that journey, engineers have several opportunities to adjust the spacecraft's flight path, to make sure its speed and direction are best for arrival at Jezero Crater on Mars.
How long would it take to go to Saturn?
At its closest, Saturn is 1.2 billion kilometers away from Earth. So with today's spacecraft technology, you'll need about eight years to make the trip.
What planet has acid rain?
planet Venus The most acidic rain in the Solar System is found on the planet Venus, where the working fluid in the cycle of evaporation, condensation and precipitation is a sulphuric acid solution (rather than water, as on Earth).
What rains on Mars?
Because of Mars' very low atmospheric pressure, any water that tried to exist on the surface would quickly boil away. atmosphere as well as around mountain peaks. No precipitation falls however.
Is there another Earth with humans?
The Kepler space telescope identified the exoplanet, and its discovery was announced by NASA on 23 July 2015….Kepler-452b.
| Discovery | |

What planet can we live on besides Earth?
Kepler-62e and Kepler-62f are thought capable of hosting life. The planet Kepler-69c is located about 2,700 light-years from Earth in the constellation Cygnus. This is an illustration of the planet, which is the smallest yet found to orbit in the habitable zone of a sun-like star.
Does it rain on Mercury?
Since Mercury has hardly any atmosphere, it does not have weather like storms, clouds, winds or rain. Its surface temperature can reach 801 Fahrenheit during the day (because it is so close to the Sun) and can drop to -279 Fahrenheit at night (because there is no atmosphere to trap the daytime heat).
What planet is the coldest?
Uranus The coldest planet in our solar system on record goes to Uranus which is closer to the Sun and 'only' about 20 times further away from the Sun than the Earth is. The lowest temperature recorded there was minus 224 degrees Celsius.
Did Venus ever have life?
The possibility of life on Venus is a subject of interest in astrobiology due to Venus's proximity and similarities to Earth. To date, no definitive evidence has been found of past or present life there.
Was Venus once habitable?
Knoll light factory. Adobe After Effects CC 2017. Venus, our vexing sister planet, was likely habitable up to 900 million years after its formation, all without the need for plate tectonics (the global geological recycling of a planet's carbon).
What planet is hottest?
Venus Because of this, Venus is the hottest planet in the solar system. The surface of Venus is approximately 465°C! Fourth from the Sun, after Earth, is Mars.
What is the oldest planet?
Jupiter formed in a geologic blink. Its rocky core coalesced less than a million years after the beginning of our solar system, scientists reported Monday in the Proceedings of the National Academy of Sciences.
Do we have 2 suns?
Our Sun is a solitary star, all on its ownsome, which makes it something of an oddball. But there's evidence to suggest that it did have a binary twin, once upon a time.
Does Earth have a sister?
Venus has long been considered Earth's twin sister. The two planets are very similar in some respects and share many physical and orbital characteristics: inner planets. varying terrains on the surface: mountains, plains, high plateux, gorges, volcanoes, crests and impact craters.
