The Solar System

the temperature of pluto is so cold that air of the kind we know would freeze

I can not find any reference to a Meridian in the Solar System.

In astronomy, there is the Earth's meridian. That's a "great circle" on the "celestial sphere". It passes through the "celestial poles" and also through the "zenith" at the observer's location.

There are only 8 planets because they scientific community kept finding other small or dwarf planets further out from Pluto. So rather than add planets to the nine as we find smaller and smaller planetoids the decision was made to just call the larger 8 planets, planets and everything else planetoids or something like that.

Planets don't "weigh"; they have a mass. Mass is that which is expressed in kilograms (or pounds, or tonnes).The seventh planet from the Sun is Uranus; its mass is 8.68e25 kilograms, or about 14.5 times the mass of Earth.

The solar system consists of the sun, eight planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune), their moons, dwarf planets (such as Pluto), asteroids, comets, and other small bodies like meteoroids. Gravitational forces and the sun's magnetic field hold the solar system together.

The Milky Way isn't in the solar system, the solar system is in the Milky Way, about 27,000 light years from the center, at the edge of one of the spiral arms.

Everything is mostly space. The diameter of the sun is 865 thousand miles, which is a bit under a million. The radius of the earth's orbit is 93 million miles, almost 100 million. Sedna, which isn't even outside the solar system, orbits 900 times as far (currently).

Earth is the major planet in our solar system that has only one moon, which is called the Moon.

This process is called accretion. It involves small particles like rocks, gas, and dust clumping together due to gravity and sticking to each other to form larger bodies like planets. Over time, these bodies continue to collide and grow in size until they become fully formed planets.

It is the fourth planet from the sun in the solar system, the last of the inner ring planets before the asteroid belt, the planet after Earth and the planer before Jupiter.

earth is the only planet with most water cant you see you live in the earth. earth is the solar systems water, plants, and human planet you know? so that's your answer eath is the planet with the most water.

Saturn is the second largest and is known for its fascinating rings

In the geocentric model of the solar system, Earth is considered to be at the center with all other celestial bodies, including the sun, planets, and stars, orbiting around it. This model was widely believed in ancient times but was later replaced by the heliocentric model, which correctly places the sun at the center of the solar system.

No, a pulsar is not a part of the solar system. Pulsars are highly magnetized, rotating neutron stars that emit beams of electromagnetic radiation, while the solar system consists of the Sun, planets, and other celestial objects that are gravitationally bound to the Sun.

The alignment of all planets would result in freak weather, planetary oscilllation (wobbling on their axis) and the apocalypse. However few planets are perfectly on the eccliptic so could not be properly algined.

The rotation of Earth on its axis is responsible for causing day and night. As the Earth rotates, different parts of the planet are exposed to the Sun's light, creating periods of daylight and darkness.

Planets in the solar system are thought to have formed from a giant rotating disk of gas and dust around the young Sun, known as the solar nebula. Small particles in this disk collided and stuck together, gradually growing into planetesimals and eventually forming protoplanets and then fully-fledged planets through accretion and gravitational interactions.

South Pole Aitken Basin (diameter 2500km) is not the largest known impact crater. That distinction lies with Utopia Planitia Basin (3500km) on Mars. However, SPA is the deepest known impact basin in the Solar System at 13 kilometers.

If proven, the hypothesized Borealis basin, on Mars, would be the largest impact basis, at more than 10000 km in diameter.

Satellites can help explore our solar system by orbiting planets, moons, and asteroids to gather data and images. They provide valuable information about the composition, atmosphere, and geology of celestial bodies, enabling scientists to study and understand the solar system in greater detail. Satellites also help to monitor space weather, track planetary movements, and support communication with spacecraft exploring distant worlds.

No. A comets tail is created when water evaporates off the comet, this can only happen when the comet is near enough to the sun for water to evaporate. The tail of a comet does not follow behind it but always points away from the sun because of the solar wind.

The study of the origin of the solar system and the universe in general is known as cosmogony. It aims to understand how celestial bodies, such as stars, planets, and galaxies, formed and evolved over time. This field of study combines knowledge from astronomy, physics, chemistry, and other disciplines to construct models of the universe's early history.

There are eight planets in our solar system. However, in the entire cosmos, there are billions of planets that orbit stars in other solar systems.

There are 176 known moons that have been discovered so far in our solar system. These are small bodies that orbit a planet or dwarf planet.

169 moons orbiting six planets (includes Earth's Moon)

7 moons orbiting three dwarf planets

There are other bodies that orbit the Sun, or that orbit dwarf planet candidates. There are as many as 58 satellites of trans-Neptunian objects (TNOs) and around 104 asteroid moons (orbit around larger asteroids).

There is only one star in our Solar System. It's called the sun. On the other hand, there are 8 planets.
One.
