The Solar System

Mercury is now the smallest 'true' planet in our solar system. Pluto was the smallest planet before the definition of a planet was revamped. Now, if you include dwarf and minor planets, the next biggest is Eris.

The four inner planets of the solar system are Mercury, Venus, Earth, and Mars. They are also known as the terrestrial planets because they are primarily composed of rock and metal. These planets are located closer to the sun compared to the outer gas giants.

Jupiter is known as the stormy planet in our solar system due to its prominent and persistent storm called the Great Red Spot. This massive storm has been raging for centuries and is larger than Earth.

All the time,

but the highest concentration of junk occures when we pass through the path of a comet. The big shows are called meteor showers and happen every year.

Some of the better-known meteor showers and their approximate dates are: Lyrids, Apr. 21; Perseids, Aug. 12; Orionids, Oct. 20; Taurids, Nov. 4; Leonids, Nov. 16; Geminids, Dec. 13.

The Earth-centered solar system was thought to be sun-centered in the 16th century by astronomers such as Nicolaus Copernicus. Copernicus published his model in 1543, proposing that the Sun, not the Earth, was the center of the solar system. This heliocentric model eventually gained acceptance over the previously held geocentric model.

The concept that all planets revolve around Earth is known as the geocentric model. This idea was proposed by early astronomers before the heliocentric model, with Copernicus and Galileo helping to advance the understanding that Earth and other planets actually revolve around the Sun.

When Galileo first observed Saturn through a telescope, he thought that it had ears. We now know that these "ears" were Saturn's rings.

Jupiter is the second superior planet with an orbit outside of the Earth's and the first one beyond the asteroid belt. Fifth planet from the Sun, the Giant Planet maintains a dignified minimum of 7.4 hundred million kilometers from the Sun. Because it has an average eccentricity of 5 percent, though, the planet never strays farther away than 8.2 hundred million kilometers. Despite its distance, its massive size makes it easily visible from Earth.

Nothing we've been able to discover. If there was life on (or more properly, "in") Saturn, it would probably be radically different from anything we know of, because Saturn is primarily a giant orb of gaseous hydrogen, with pressures that increase astronomically with depth.

The Milky Way galaxy is significantly bigger than our solar system. Using the Oort Cloud as a marker to signify the outer edges, our solar system has a diameter of about 3.2 light years (or 200,000 AU). In comparison, the Milky Way galaxy is approximately 100,000 light years across, which makes it 31,250 times bigger than our solar system.

Ganymede, a satellite [of Jupiter] is the largest moon in the solar system. It is actually bigger than Mercury.

The smallest main sequence star detected so far is called OGLE-TR-122b.

It has a radius of 0.12 that of our Sun which means it is only 20% larger than Jupiter and has a mass of about 100 times that.

Astronomers describe the smallest star as a "core burning star," like our Sun. But prevailing theory never anticipated such a diminutive star, since the standard fusion model of stars required a minimum gravitating mass considerably greater than that of Jupiter.

The smallest non main sequence star is a neutron star with a diameter of 12km - equal to about the length of Manhattan Island from the tip till the end of Central park.

Mercury, the closest planet to the sun, has an orbital period (year) equal to 88 Earth days.

The largest ball of hot gas in the solar system is the Sun. It is a massive, luminous sphere of plasma that provides light and heat to the planets in our solar system.

Earth, Mars, and Venus are the three planets in our solar system that show signs of oxygen in their atmosphere, although the levels and presence of oxygen vary significantly among them. Earth has a rich oxygen atmosphere, while Mars and Venus have much lower levels of oxygen.

Pluto was reclassified as a dwarf planet in 2006 by the International Astronomical Union due to its small size and its orbit, which overlaps with Neptune's. These characteristics did not meet the criteria for a planet as defined by the IAU, hence the reclassification.

Yes, Jupiter is the largest planet in our solar system, but it is not the most dense or most massive. Saturn is the least dense planet, while Neptune is the most massive due to its high density composition.

The hottest place in the Solar System is the Sun's core, where temperatures can reach up to 27 million degrees Fahrenheit (15 million degrees Celsius). The surface of the Sun is cooler, but still extremely hot, with temperatures of about 10,000 degrees Fahrenheit (5,500 degrees Celsius).

Venus is the hottest planet. Although it is only the second closest to the sun, its thick Carbon Dioxide atmosphere causes it to have a severe runaway greenhouse effect. Mercury is the closest planet to the sun, but it has no atmosphere therefore more of the suns light is reflected back out into space.

Earth is more than 5 times denser than water. Of all the planets in the solar system, only Saturn is less dense than water.

Gravity is the force that connects the solar system to the sun.

Mars has two very small satellites that orbit very close to its surface. The first spacecraft to visit Mars was the Mariner 4 back in 1965 and several others have visited since that time.
they have 2 satillites
Mars has two natural moons orbiting it. Named Phobos and Deimos.

They are known as terrestrial planets. They are Mercury, Venus, Earth and Mars.

In general terms any unusual natural event was seen as a sign from the Gods, or a portent of something that was to happen.

In Norse Mythology the Sun was chased across the sky every day by the Wolf Skoll. Skoll was intent on devouring the Sun and it was believed that Skoll was taking bites out of the Sun during the Eclipse.

Of course the Sun would magically reappear to light the world but the skalds told that at Ragnarok then Skoll would be sated and darkness and ice would cover Midgard.
