What is the length between the Sun and Mercury?
Size and Distance From an average distance of 36 million miles (58 million kilometers), Mercury is 0.4 astronomical units away from the Sun. One astronomical unit (abbreviated as AU), is the distance from the Sun to Earth. From this distance, it takes sunlight 3.2 minutes to travel from the Sun to Mercury.
What is the closest distance between Mercury and the Sun?
29 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).
What is the distance from the center of Mercury to the center of the Sun?
When Mercury is closest to the sun, it is only 46 million kilometers (29 million miles) distant, but when the planet is rounding the opposite focus of its orbit, it is 70 million kilometers (43 million miles) away from the sun.
How far is Mercury from the Sun in light minutes?
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 …
Why is Mercury close to the Sun?
Like Venus, Mercury orbits the Sun within Earth's orbit as an inferior planet, and its apparent distance from the Sun as viewed from Earth never exceeds 28°. This proximity to the Sun means the planet can only be seen near the western horizon after sunset or the eastern horizon before sunrise, usually in twilight.
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.
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).
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.
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 does Neptune rain diamonds?
Take the conundrum, for example, of how the chemical reactions inside of Neptune and Uranus may cause diamonds to rain down on the planets' cores. Under immense pressure deep below the planets' surfaces, carbon and hydrogen atoms are smushed together, forming the crystals.
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.
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.
What rains in 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 rains Uranus?
Deep within Neptune and Uranus, it rains diamonds—or so astronomers and physicists have suspected for nearly 40 years. The outer planets of our Solar System are hard to study, however. Only a single space mission, Voyager 2, has flown by to reveal some of their secrets, so diamond rain has remained only a hypothesis.
What rains on Pluto?
Glaciers made of nitrogen ice creep across its surface, hazes cycle through its puffy atmosphere, and dark organic compounds rain down. Pluto's hazy skies form a halo around the dwarf planet in this backlit image taken by New Horizons.
What rains Jupiter?
New research by scientists apparently shows that it rains diamonds on Jupiter and Saturn. In fact the planets have the capability to create 1000 tonnes of diamonds a year.
How many Suns are there?
There Is Only One Sun The word “sun” is often used to describe many multitudes of stars in our galaxy and beyond, but doing so is a misnomer. The Sun is the name of our star, just as Sirius is the brightest star in Canis Major.
How many galaxies are in space?
While estimates among different experts vary, an acceptable range is between 100 billion and 200 billion galaxies, said Mario Livio, an astrophysicist at the Space Telescope Science Institute in Baltimore, Maryland.
How many black holes are there?
Most stellar black holes, however, are very difficult to detect. Judging from the number of stars large enough to produce such black holes, however, scientists estimate that there are as many as ten million to a billion such black holes in the Milky Way alone.
Is the space infinite?
The observable universe is finite in that it hasn't existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding).
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.
Who discovered Earth?
The first person to determine the size of Earth was Eratosthenes of Cyrene, who produced a surprisingly good measurement using a simple scheme that combined geometrical calculations with physical observations.
How cold is space?
In fact, it doesn't actually have a temperature at all. Temperature is a measurement of the speed at which particles are moving, and heat is how much energy the particles of an object have. So in a truly empty region space, there would be no particles and radiation, meaning there's also no temperature.
Can plants grow on Mars?
Research suggests Martian soil has some of the nutrients plants need to grow and survive (see “Plants' Nutrients,” right). But because of Mars's extremely cold conditions, plants such as Watney's potatoes would need to grow inside a controlled environment, such as his Hab.
Which planet is full of diamonds?
For centuries, astronomers have been fascinated by Saturn. After all, she has been hailed as the precious jewel of our solar system, one of the most beautiful planets. And while her rings have mesmerised us for centuries, it is even more amazing to realise that it quite literally rains diamonds out there!
What planet is made of diamonds?
In 2012, Yale University scientists published a study announcing the identification of a planet rich in diamonds. Called 55 Cancri e, the planet is "possibly covered in diamond, rather than water and granite," scientists explained at the time. The exoplanet is twice the size of Earth but has eight times its mass.
