Is the earth and globe are round?


Answer:
To a first-order approximation the Earth is round. This
is due to gravity. Gravity pulls with equal strength in all
directions; therefore any variations from a spherical
shape will lead to gravitational forces that
bring the shape back into that of a sphere.

This is without considering the rotation of the earth,
however. The rotation of the earth adds centrifugal
effects, which cause the earth to bulge slightly at
its equator and flatten slightly at its poles.
(This is like twirling a rock on the end of a string
and then letting go--the rock flies away from the
twirler.) Because of these centrifugal effects, the
distance from the center of the earth to the surface
of the earth is about 0.33% shorter at the poles
compared to the equator.

What are the names of 63 moons in the planet Jupiter?

Yes because that is how many have been recorded so far...but there most likely are more moons orbiting Jupiter...you never know..but like i said there have been 63 satellites orbiting Jupiter.

How many gaseous planets in our solar system?

There are 4 planets that are considered the "Gas Giants." Jupiter, Saturn, Uranus, and Neptune. Uranus and Neptune are also called the "Ice Giants." All of the planets have gases in their composition, but the Gas Giants have the highest amounts.

Why does it take Neptune 165 years to revolve around the sun?

Answer

A complete orbit.

Answer

Neptune actually takes exactly 164.79 years to complete an orbit. Scientifically rounded up, it's 165 years for a complete orbit.

Which is the coldes planet?

Planets vary widely in temperature from extremely hot to extremely cold. In our solar system the hottest planet is Venus, with surface temperatures of 850 degrees Fahrenheit while the coldest is Uranus at -371 degrees Fahrenheit.

What 2 planets are farthest from the Sun?

Mercury

Venus

Earth

Mars

Jupiter

Saturn

---------

Uranus

Neptune

(Pluto)

as these days Pluto is no longer considered a planet, apparently.

What object joined the Solar System in May 1930?

Nothing.

You may be referring to the planet Pluto, which was DISCOVERED in 1930, but it had in all probability been part of the solar system since the Sun ignited 4.5 billion years ago.

Where was the matter in the solar system before the solar system existed?

The matter that makes up the solar system, including the Sun, planets, and other celestial bodies, was originally present in the form of a giant molecular cloud or interstellar cloud within our Milky Way galaxy. These clouds are composed primarily of gas and dust, mainly hydrogen and helium, along with trace amounts of heavier elements.

These molecular clouds are immense in size and are held together by their own gravity. Over time, certain regions within these clouds can become denser and more concentrated due to various factors, such as shockwaves from nearby supernovae or the gravitational influence of other nearby massive objects.

When a region of a molecular cloud becomes sufficiently dense and gravitationally unstable, it can collapse under its own gravity. As this collapse occurs, the material within the cloud starts to clump together, forming knots of gas and dust. Within these knots, further gravitational collapse can lead to the formation of protostars and, eventually, entire star systems like our solar system.

In the case of the solar system, the matter within the collapsing cloud collected at the center to form the protostar that would become the Sun. The surrounding material flattened into a rotating disk, out of which planets, moons, asteroids, and comets gradually formed through a process known as accretion. The planets and other objects in the solar system, including Earth, are essentially made up of the same material that was once part of the molecular cloud.

In summary, the matter in the solar system was originally part of a giant molecular cloud within our galaxy before it collapsed under its own gravity to form the various celestial bodies we observe today.

Why is the sun considered the center of the solar system?

The sun has the majority of the mass in the solar system. Gravitational attraction varies directly as the magnitude of the mass. The sun therefore has the greatest gravitational effect in the solar system.

Which the largest solar system in universe?

As we only know of our own in any definite terms we cannot say which is the largest. Nor are we ever likely to be able to do so.

How is Uranus related to the other plaets?

In our Solar System, Uranus is:

  • The second-farthest planet from the Sun. Neptune is farther still.
  • The fourth largest planet, after Jupiter, Saturn, and Neptune.

What other planets in the solar system have wind?

Venus, Earth, Mars, Jupiter, Saturn, Neptune and Uranus all have wind. The atmosphere on Mars is very thin, but there's still enough wind for it to have dunes and dust storms.

That's all the planets except Mercury. I don't know that Mercury doesn't have wind, and in fact I suspect it does, but I've never heard positively one way or the other.

What unit do astronomers usually use to measure distances in the solar system and how is it abbreviated?

Distances within the solar system are usually reported in kilometers or AUs.

1 AU = average distance of Earth from the Sun, about 150 million kilometers (149,597,871 km).

  • Nearby . . . miles or kilometers
  • Out past that . . . AU (Astronomical Units)
  • Out past that . . . Light Years
  • Out past that . . . Parsecs

Will Saturn float or sink if you place water?

Float. The problem is whether you can find a bathtub big enough for it :D

Is it true or false that a heliocentric model of the solar system has earth at the center?

False!!!!

The ancients of Greece and Rome and earlier thought the Earth (Terrestium) was the centre of the universe.

However, a Polish astronomer named Nicolaus Copernicus, showed that the Sun was the centre of the known system of the day.

He published in 1543, his work on the Heliocentric system, ; 'De revolutionibus orbium coelestium' ( On the Revolution of Heavenly Spheres.). It deduced : -

#1 The Earth is one of several planets revolving around a stationary sun in a determined order.

#2 The Earth has three motions: daily rotation, annual revolution, and annual tilting of its axis.

#3 Retrograde motion of the planets is explained by the Earth's motion.

#4 The distance from the Earth to the Sun is small compared to the distance from the Sun to the stars.

What is the order in which the planets were discovered in?

First . . . Earth

Tied for second . . . Venus, Mercury, Mars, Jupiter, Saturn

Then, in order . . .

Uranus

Neptune

Pluto

. . . other dwarves

Extra-solar planets

What does heliocentric mean and how does it affect us?

Heliocentrism is the astronomical model in which the earth and planets revolve around the Sun in the center of the Solar System. Heliocentric is the adjective describing this system.

What caused the nebula that formed our solar system to rotate?

1) The collapse is not bound to be perfectly symmetrical. Some pieces of matter will randomly move in one direction, or in another. The net result is that there is some rotation.2) Roughly speaking, anything that rotates will continue rotating.

If the distance between earth and the sun were doubled what would happen?

In that case, among other things:

  • It would be a lot colder on Earth. Perhaps too cold for most multicellular life.
  • Earth would move more slowly around the Sun.
  • The year (the time for one orbit) would take longer; you can calculate how much longer, using Kepler's Third Law.

What condition of earth makes IT JUST RIGHT FOR LIFE?

Temperature is an important factor. Many of the following may also contribute:* The presence of enough water.

* The ABSENCE of free oxygen in the early atmosphere - though this may actually be quite common, since oxygen tends to bind to other elements.

* Earth's age - it's possible that life takes a long time to develop.

* Earth's magnetic field may help protect us from dangerous radiations.

You can find quite a lot more such conditions, if you search for "fine-tuning".

IMPORTANT NOTE: Many will say that such "fine-tuning" proves that life was designed by a creator; actually it doesn't, since there are billions of billions of planets to "chose" from. In that case, it might not be so surprising that A FEW of those planets did develop life.

How much of the solar systems matter is in sun?

About 99.8%. An cosmologist's joke has an intragalactic survey report reading, "Primary (the Sun), a major planet (Jupiter), some debris."
