What is Jupiter's minimum distance from earth?

The minimum distance of Jupiter from Earth (i.e. the closest approach) is equal to about 588.5x10^6 km.

What are the names of the satellites or robots that have landed on Jupiter?

None yet. Pioneer 10 did a fly-by in 1973.

Six years later, Voyager did a fly-by.

The Cassini probe flew by in 2000, en route to the planet Saturn.

In 2007, the New Horizons probe flew by, on the way to Pluto.

The Galileo orbiter began orbiting Jupiteron December 7, 1995, and was subsequently intentionally crashed into the surface on September 21, 2003.

Why is Jupiter's period of revolution longer than the inner planets' periods of revolution?

Jupiter's period of revolution is longer than the inner planets' periods of revolution because it is so much farther away from the Sun. Jupiter has to travel over 2 billion miles (3.2 billion kilometers) father than Mars to get around the Sun. Jupiter's orbit is almost 4 times longer than that of Mars in distance. Also Jupiter orbits more slowly. So it takes Jupiter 6 times longer than Mars to orbit the Sun. (Mars is is farthest inner planet from then Sun.)

What planet hit juptier and gave it the great red dot?

A planet did not hit Jupiter, a hurricane started which is called the Great Red Spot.

Was Jupiter Always So Big?

Yes, Jupiter has always been large compared to other planets in our solar system. Its size is a result of its composition, primarily made up of gases like hydrogen and helium. Since its formation billions of years ago, Jupiter's gravity has allowed it to capture a vast amount of gas and debris in its vicinity, contributing to its immense size.

Did boys come from Jupiter?

No, boys do not come from Jupiter. Boys are born on Earth just like girls, through the natural process of reproduction between male and female humans. Jupiter is a planet in our solar system and does not play a role in the birth of children.

Can you see Jupiter from Liverpool in UK tonight?

Yes - depending on the weather, of course. If you look South-West at around 6pm (without any buildings in the way, as it'll be low and near the horizon) you'll be able to see Jupiter just "below" the Moon. Here's a star chart showing you where to look: http://www.schoolsobservatory.org.uk/astro/esm/sky/hz18.shtml

Can Venus be seen in evenings in September 2009?

No. You can see Jupiter in the evenings in September, but Venus isn't visible.

Venus can be seen close to sunrise - around 3am in the UK.

How does man specify interstellar distances when using the speed of light?

Our common terms for distance, miles and kilometers, are useful enough to measure distances around town, and even around the country. But for distances beyond our solar system, it's cumbersome to carry around a bushel-basket full of zeroes to add to the distance measurements.

So we typically phrase things in terms of "light-years", the distance that light would travel on one year. Light moves at 186,000 miles or 300,000 kilometers per SECOND, so a light year is quite a distance; 186000 * 60 * 60 * 24 * 365.24 miles, which is 5,869,552,900,000 miles. The nearest star, Proxima Centauri, is four times FURTHER away at 4.2 light-years, so you can see that the distances to even the nearer stars are quite cumbersome when expressed in conventional units.

In metric terms, we have, perhaps, another way to go. The standard distance is the "meter", and latinate prefixes are used to denote larger quantities, such as the kilo-meter, for 1,000 meters; about 6-tenths of a mile.

In computer terms, the word "byte" is used to designate the storage space required to store one ASCII character. A "kilo-byte" is a thousand bytes (actually, 1024 bytes, but close) and a "megabyte" is a million (plus a bit) bytes. A gigabyte is a billion, and a terabyte is a trillion.

So, let's extend that to astronomy. One light year is 5.8 tera-miles.

Can you sink on Jupiter?

i think you can because if it will suck you in then you will sink It's outer surface is made up of gas so you will sink but it has a solid core so you might land on something.

Is Jupiter round?

In general, planets are considered round, although they may not be perfectly round. Jupiter's equatorial radius is about 71,500 km, and its polar radius is about 66,800 km, indicating that it bulges at the equator; it is a little "stouter" than it is "tall". Earth has the same general characteristic. No object in the solar system has a geometrically perfect shape, and it is not likely that any objects in the universe do, either.

What is the Scale height of Jupiter?

By considering P(h) = P(0) * exp(-(mgh/kT)) - (where P(h) is the pressure result of the equation; P(0) is the pressure at the "surface" of the planet; m is the mass of the molecule that is predominant in the atmosphere (in kg); g is the gravitational acceleration present on the planet; k is Boltzmann's constant; T is mean observed temperature (in Kelvin)) We can then analyse what height is needed for P(h) to be equal to 1/e of the surface value: the scale height h(0) = kT/mg for P(h) to be equal to 1/e, and by substituting in standard values, and assuming a predominantly hydrogen gas atmosphere, and using g=GM/r^2, we derive the result (that varies according to the different values of g, m, and T that you use): h(0)(Jupiter) = ~20km Have fun ;-)

What are three facts about Jupiter?

  • Jupiter is the largest planet. It is so large that all the other planets could fit inside it with space left over.
  • Jupiter is the 5th planet from the Sun
  • Jupiter is one of the four gas giants - its surface is covered by a very dense atmosphere
  • People could not live on Jupiter, as it has no surface to walk on and no breathable air.
  • There are colored bands of clouds, which have varying chemical compositions.
  • Jupiter spins the fastest of all planets - it rotates (a day) in just under 10 hours.
  • There are faint rings of dust around Jupiter (as with Saturn's icy rings).
  • The large red spot on Jupiter is a storm caused by internal heat, like hurricanes on Earth.
  • The red spot on the surface of Jupiter has been there since the time that Galileo Galilei first observed the planet with a telescope in 1610.
  • As it is made entirely out of gas, technically it has no surface.
  • It was named after the primary Roman god (equivalent to Zeus of Greece).
  • One of its moons (Europa) is theorized to have the only other source of liquid water in our Solar System, aside from Earth.
  • One of its moons (Io) is the only volcanically active moon in the Solar System. It erupts liquid sulfur onto the surface of the moon.
  • The Voyager 1 probe was the first to take close-up pictures of Jupiter in 1979.
  • Jupiter's atmosphere is mostly involved in storms with very high speed winds.
  • It has a small rocky core buried in an atmosphere so dense that at the bottom it is solid hydrogen.
  • Its average distance from the Sun is 778 million kilometers (484 million miles).
  • It has 63 known moons. Most of them are small, but 4 are larger than Earth's Moon, and larger than the dwarf planet Pluto.
  • Jupiter's volume could hold 318 Earths and its diameter is also 11 times larger.
  • The planet gives off radio waves that can be detected on Earth.
  • It takes 12 Earth years for Jupiter to make one orbit of the Sun.
  • it is an average of 44 light-minutes from Earth to Jupiter. (34 light-minutes from Earth's orbit to Jupiter's orbit).
