The Solar System

The distance between planets are measured in millions of kilometers while the distance between solar systems are measured in light years while the galxies and the universe are measured in AU (astronautical units)

Yes much colder, in fact it's the coldest place ever measured in the Solar System. Neptune has an internal heat source (it radiates more heat than it receives from the Sun) though it is still quite frigid at the cloud tops.

Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.

Gravity is the force responsible for the formation of the solar system, the movement of objects within the solar system, and holding together stars and galaxies. It is a fundamental force of nature that acts over large distances and is essential for understanding the structure of the universe.

There are eight planets in our solar system (from closest to sun to furthest); Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.

A further five dwarf planets are also recognised; Ceres (in the asteroid belt between Mars and Jupiter), Pluto, Haumea, Makemake and Eris.

Mars is called the rusty planet because of the large amounts of iron oxide (rust) on the surface.

The four main parts of the solar system are the Sun, the eight planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune), their moons, and other smaller celestial objects like asteroids and comets.

It takes about 27.3 days for the Moon to revolve once around Earth.

Mars is the fourth planet from the sun. The order of the nine planets in the solar system is mercury, venus, earth, mars, jupiter, saturn, uranus, neptune, pluto. Mars is smaller than the earth. Venus is about the same size as the earth. Mars is not very tiny like mercury and pluto.

= Answer = None The following spacecraft have passed the last known body, ie Pluto Pioneer 10 and 11 Voyager 1 and 2 New Horizons will leave the solar system after flying past Pluto in July 2015. The solar system does not really end with Pluto. Besides the planets, there is a thin haze of dust (some of it bunched into comets). Any of this dust that is nearer to the Sun than to any other star may be in the gravitational hold of the Sun and so counts as part of the solar system. Voyager 1 is now near the Sun's heliopause [See Link]. The heliopause is the theoretical boundary where the Sun's solar wind is no longer great enough to push back the stellar winds of the surrounding stars. = Answer = It is true that none of the 5 spacecraft have to date left the physical environment of the solar system, however all 5 of them have sufficient kinetic energy to escape the Sun's gravity. Their escape from the solar system is therefore guaranteed, nothing that man or nature can do, short of an asteroid impact, can stop them from leaving the solar system. By having acquired sufficient velocity to exceed solar escape velocity, they can be said to have left the solar system. Even New Horizons, which will not complete its Pluto reconnaissance mission until 2014, has already escaped from the solar system.

Voyager 1 and Voyager 2 have both left the heliosphere, but neither has left the solar system. The edge of the solar system is considered to be the outer boundary of the Oort Cloud, The exact width of the Oort Cloud is not known, but its estimated that it would take Voyager 2 about 300 years to reach the inner boundary of it. To reach the outer boundary of the Oort Cloud, truly leaving the solar system, would take Voyager 2 something like 30,000 years.

The moon is exceptionally bright when it is in a "fuller" phase. In some instances, you can read by moonlight. The moon, however, only reflects light. The second brightest object in the night sky next to the moon is Venus. It, too, reflects light. Sirius, the Dog Star, is the brightest star in the night sky.

This depends on how fast you are travelling. The nearest star to our solar system is Proxima Centauri, which is located 4.2421 light years away (or 40,133,364,737,735km). The fastest man-made object to date is the Helios 2 solar probe, which had a speed of 252,800km/hr. If you travelled at this speed, it would take you 158755398.5 hours, or 6614808.3 days or 18122.8 years to get there.

The planets orbit around the sun.

There are currently eighteen known planets and two protoplanets in our solar system. We are always discovering more, so this may change. This is also widely debated, because different scientists think differently about how "planet" should be classified. It is common for scientists to only acknowledge eight planets in our system, and it is true that there are eight main planets. However, there are also ten dwarf planets, which are a form of small rocky planet.

Saturn is less dense than water. So the Answer is Saturn.

Solar winds can cause disruptions in Earth's magnetosphere, leading to geomagnetic storms that can interfere with satellite communications, power grids, and navigation systems. They can also cause beautiful auroras to appear at the poles. Additionally, solar wind particles can contribute to the erosion of the Earth's atmosphere over time.

Gregor Mendel is the father of genetics.He found the inheritance using pea plants.

Nothing yet has PROVED the existence of the Kuiper Belt, the theoretical "shell" of primordial material left over from the formation of the solar system. However, the recent discoveries of several near-planetary objects such as Sedna and Eris beyond the orbits of Neptune and Pluto have given greater evidence to support this theory.

"Proof" will need to wait for more powerful telescopes or for robotic probes to go out and see what's there.

Venus is completely covered by sulfuric acid clouds.

The gas planets (Jupiter, Saturn, Uranus, and Neptune) are essentially made up of just clouds and gas. There's nothing much being covered, except fluids like liquid hydrogen.

Very deep down there may be rocky cores.

The distances between Earth and the Moon change due to the elliptical shape of the Moon's orbit around Earth. This causes the Moon to be closer at certain times (perigee) and farther away at other times (apogee). Overall, the average distance between Earth and the Moon is about 384,400 kilometers.

The two main bodies in terms of mass in our solar system are the Sun and Jupiter. The Sun contains over 99% of the total mass in the solar system, while Jupiter is the largest planet and contains most of the remaining mass after the Sun.

Yes, there are many other objects in the solar system besides planets. Some of these include moons, asteroids, comets, dwarf planets, and Kuiper Belt objects. Each of these objects plays a unique role in shaping the dynamics of our solar system.

That would almost certainly have to be Mercury. The intense heat would boil off any volatiles like water during the formation of Mercury, as well as rapidly boiling off any water that arrived in any comet or meteor impact. Mercury is also extremely small with minimal gravity and virtually no atmosphere, which would also lead to extremely rapid loss of any water.

Venus is the only other planet closer to the sun and hotter than the earth, and it's thick atmosphere does hold plenty of water vapor, and there is almost certainly quite a bit of water trapped within the rocks under the surface.

Mars certainly has water trapped in the subsurface rock, the gas giant planets have and hold water within in their thick heavy gravity atmospheres, and icy bodies like Pluto have abundant water-ice. When things are that cold, water in the form of ice is essentially a rock or mineral.
