How close does Mercury get to our Sun?
Mercury is the closest planet to the Sun. Its orbit around the Sun is very elliptical, like a stretched out circle, compared to those of the other planets. Mercury's distance from the Sun ranges from 28.6 million miles (46 million km) to 43.4 million miles (69.8 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 far is Mercury from the Sun in light minutes?
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 far is Mercury from the Sun in light seconds?
Mercury 0.387 193.0 seconds or 3.2 minutes Venus 0.723 360.0 seconds or 6.0 minutes Earth 1.000 499.0 seconds or 8.3 minutes Mars 1.523 759.9 seconds or 12.6 minutes Jupiter 5.203 2595.0 seconds or 43.2 minutes Saturn 9.538 4759.0 seconds or 79.3 minutes Uranus 19.819 9575.0 seconds or 159.6 minutes Neptune 30.058 …
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.
Is there a planet behind the Sun?
Unfortunately, the forces of gravity conspire to make this hidden planet idea completely impossible. Most importantly, when someone tells you there's a hidden planet on the other side of the Sun, just remember these words: No. Nooooo.
Is Mercury visible from Earth?
As an evening star, Mercury appears in the western sky, setting about an hour after the sun. As a morning star, it appears in the eastern sky, rising about an hour before the sun. There must be a clear, unobstructed horizon on these occasions. Mercury usually appears as a bright "star" with a yellowish or ochre hue.
How far is one Lightyear in space?
about 6 trillion miles Coe et al. For most space objects, we use light-years to describe their distance. A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km).
Can Mercury support life?
Potential for Life Mercury's environment is not conducive to life as we know it. The temperatures and solar radiation that characterize this planet are most likely too extreme for organisms to adapt to.
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.
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.
Do we have two suns?

Is there a 2nd sun?
Nemesis is a theoretical second sun in our solar system, a dwarf star named after the Greek goddess of vengeance. In the English vocabulary, the word nemesis has come to mean downfall or ruin, and surely nothing good can result from a celestial body bearing this moniker.
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.
What planet is closest to Earth today?
Although Venus is the planet that comes closest to Earth as it sweeps by on its orbit, Mercury stays the closest to Earth the longest, according to a commentary published Tuesday (March 12) in the magazine Physics Today.
How many light-years is the Milky Way?
about 100,000 light-years Our galaxy probably contains 100 to 400 billion stars, and is about 100,000 light-years across. That sounds huge, and it is, at least until we start comparing it to other galaxies. Our neighboring Andromeda galaxy, for example, is some 220,000 light-years wide.
How many galaxies are there?
In total, Hubble has discovered about 100 billion galaxies in the Universe. However, after James Webb is fully operational, this number will probably increase to 200 billion. Moreover, scientists are not sure that even 200 billion galaxies is the final figure.
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.
Can humans survive on Pluto?
As such, there is simply no way life could survive on the surface of Pluto. Between the extreme cold, low atmospheric pressure, and constant changes in the atmosphere, no known organism could survive.
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.
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 planet is human landed on?

What planets can humans live on?
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.
Is Earth going to lose the Moon?
Calculations of the evolution of the Earth/Moon system tell us that with this rate of separation that in about 15 billion years the Moon will stop moving away from the Earth.

Does the Earth have two sons?
The placement of the planets appears out of whack compared to other systems, and it's missing the most common planet in the galaxy, the super-Earth.) So, if not for some cosmic event or quirk, Earth could have had two suns. But we don't.
Is there a black hole in our solar system?
'Black hole' wandering near our solar system detected by Hubble Space Telescope. AUSTIN (KXAN) — NASA announced this week that the Hubble Space Telescope detected what might be a wandering 'black hole' nearly 5,000 light-years away in the Milky Way Galaxy.

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.
