Planetary Science

As of current research, there is no direct evidence to confirm the existence of planets orbiting around VY Canis Majoris, which is a red supergiant star. However, due to its massive size and advanced stage of evolution, it is considered unlikely that planets could have formed and be stable in its vicinity.

Uranus. Because of it is the 2nd planet away from the sun.

All planets are formed form the remains of the solar nebular.

Atmospheric pressure is an important factor in keeping liquid water on the surface of a planet.

With no atmosphere, liquid water would quickly escape into space. It would depend on various factors such as the temperature and escape velocity of the planet of course.

Scientists think liquid water existed on Mars in the past when the atmosphere was a lot denser.

Water does exist on the surface Mars, but only as ice.

Mercury, Venus, Earth, and Mars are known as terrestrial planets because they are primarily composed of rock and metal. They are relatively small and have solid surfaces, unlike the gas giants in our solar system. They are also located closer to the Sun compared to the gas giants.

Planets like Jupiter, Saturn, Uranus, and Neptune are likely to have visible northern lights, also known as auroras. These planets have strong magnetic fields and atmospheres that can interact with solar wind to create auroras similar to those seen on Earth.

The concept of helio centric motion of the earth and planets was proposed by Nicolaus Copernicus (1473-1543) in his works 'De Revolutionibus Orbium Coelestium'- (About the revolutions of The heaveanly Spheres.).

Europa is an icy moon of Jupiter, and its surface is covered with a layer of water ice. It does not have dirt or gravel like we find on Earth.

We know next-to-nothing about the surface of Saturn. We can guess that something at least resembling gravel exists there, because it exists on Saturn's moon Titan.

The sun produces light. By definition, something that reflects light does not produce light itself (allowing for exceptions like light reflection off the surface of a lightbulb that isn't turned on, for example).

the "loops" are formed by the charge plasma fallowing the field lines of the sun's electromagnetic field. the loops are caused by the binding up and distortion of the magnetic field due to asymmetric rotation of the sun. The the EM field stores energy in the "loops". when the field becomes stressed the field breaks and releases its stored energy.

The main sequence stars located at the bottom right of the Hertzsprung-Russell diagram are the least massive. These stars are low in temperature and luminosity, such as red dwarf stars, which have masses less than about 0.4 times that of the Sun.

The layer that is situated farthest from the planet's center is invariably the one

that contains the surface. This is the well-known law of Radius and Diameter, the

great Roman and Greek philosophers who settled their differences and teamed up

in the second Century C.E., a time of great turmoil in the ancient world.

My very excellent mother just served us nine (pizzas).

That kind of depends on where you consider the boundary of "the solar system" to be.

It's currently in the "heliosheath" and will probably reach the heliopause... which is one reasonable definition of "outside the solar system"... within the next ten years or so. Voyager 1, which is further away and moving faster, is expected to reach this boundary in about 2015, but Voyager 2 reached the heliosheath significantly closer to the Sun than Voyager 1 did... this boundary appears to be "dented" in the direction that Voyager 2 is heading.

Voyager 2 is well outside what most non-scientists think of as "the solar system" already... it's over twice as far from the Sun as Pluto is, for example.

In our solar system, neither Mercury nor Venus have any moons.

For the 300+ extra-solar planets which orbit other stars, we have no way of detecting if the planets have any moons, although it is probable that many do. We're at the edge of our technology just detecting the planet.

In theory, an infinite amount of planets have no moons.

The planets closest to the sun are Mercury, Venus, Earth, and Mars. These planets are small and rocky, with solid surfaces, and they are known as the terrestrial planets. They have shorter orbital periods and higher average densities compared to the outer gas giants.

Saturn is the 6th planet from the sun.

No, there are currently only 8 recognized planets in the solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Pluto, once considered the ninth planet, has been reclassified as a dwarf planet.

The Earth rotates the slowest near the poles and fastest at the equator due to differences in circumference at various latitudes. At the poles, the rotation speed approaches zero as the diameter is significantly smaller than that at the equator.

No planet has "disappeared" (at least not from our solar system). You are probably referring to Pluto. Pluto used to be considered a planet, but scientists have discussed this topic and now it is just considered an asteroid.
