The Solar System

Ever wondered if there is life on Mars? Or if Jupiter has five moons? Look no further; here is the category concerning all questions about our solar system and the known planets!

4,302 Questions

What is the most common element in the solar system?

The most common elements in space are Nitrogen and Oxygen. There is also Hydrogen and Argon. Surprisingly, there is more Nitrogen in space than Oxygen.

What is the largest plant in your solor system?

The largest plant in our solar system is Jupiter, a gas giant planet with no solid surface. It has a diameter of about 86,881 miles (139,822 kilometers), making it more than 11 times wider than Earth.

What marks the outer boundary of our solar system?

The heliopause marks the outer boundary of our solar system. This is where the solar wind from the Sun meets the interstellar medium of space.

Why is the Solar System called the Solar System?

The Latin word for "Sun" is "Sol", so the word "solar" means "concerning the Sun". So, the system of planets around the Sun is the "solar system".

Solar=Sun is the rounded up answer.

What is a kyper belt?

The Kyper Belt is the region far outside the orbit of Neptune where objects, also known as transneptunian objects, orbit the sun. These objects can differ from dwarf planets, like Pluto, to asteroids or other debris. Their origin is believed to be that they are leftovers from when the solar system was very young and were thrown out there by the gravity of the current planets.

How are the earth and sun alike or different?

That withstanding their differences, both the Earth and Sun share similarities. Both bodies are relatively round. The Sun and Earth are also depressions in the space and time fabric - that is they have gravitation. Both bodies are similar in that they also influence each other with their gravities. Another shared aspect is that both are part of and integral to the same Solar System and Milky Way Galaxy

The fact that the Voyager spacecraft continue to speed out of the solar system even though its rockets have no fuel is an example of?

The Voyager spacecraft continues to speed out of the solar system due to its initial velocity and the lack of significant forces acting to slow it down in the vacuum of space. This is an example of Newton's first law of motion, also known as the law of inertia, which states that an object in motion will stay in motion unless acted upon by an external force.

When was the word dwarf used?

The word "dwarf" has been in use since the late 16th century, ultimately originating from the Old English word "dweorg." It has historically been used to describe individuals with abnormally short stature as well as mythological or fantastical beings of small size.

What was the frost line of the solar system?

The frost line of the solar system is the distance from the sun where temperatures are low enough for volatile compounds like water, ammonia, and methane to condense into solid ice grains. This line is roughly located between the orbits of Mars and Jupiter in our solar system.

Is the sun the densest object in the Solar System?

No. The densest known object in the solar system is the Italian Laser Relativity Satellite with a density of 15.85 g/cm³. There are small iron meteors that orbit the sun, and at 7-8 g/cm³, these would be the densest natural objects in the solar system. Of the major bodies in the solar system, the Earth is the densest, at 5.52 g/cm³. The density of the Sun is 1.41 g/cm³.

How do the planets move in the solar system?

The planets in our solar system move in elliptical orbits around the Sun due to the gravitational pull of the Sun. Each planet travels at a different speed depending on its distance from the Sun, with closer planets moving faster than those farther away. Additionally, the planets rotate on their axes as they orbit the Sun, creating day and night cycles.

What if the sun did not produce light and heat?

The sun is essential to life on this planet, so if the sun was not producing light/heat - life on this planet would no longer exist.

The planet that is one astronomical unit from the sun?

The planet that is one astronomical unit (AU) from the sun is Earth. An astronomical unit is defined as the average distance between the Earth and the Sun, approximately 93 million miles (150 million kilometers).

How much of the planetary mass of the solar system does Jupiter contain?

By my own calculations Jupiter counts for around 0.097% of the mass of the Solar System.

The Sun on the other hand accounts for about 99.86%. After the mass of the Sun you have 0.14% of the mass of the solar system to distribute among the planets. Of this Jupiter takes up almost 0.10%

Is there gravity on other planets in the solar system?

Yes there is gravity on other planets. In fact, there is gravity on object that has mass. That gravity is just really small for objects with little mass. We only see gravity like we experience on Earth when the mass becomes really large. If you require proof that those other planets have a gravitational pull you need only remember that NASA has sent multiple space probes to other planet and put them into orbit around that planet. An impossible feat for an object what has no gravity.

Why is the system of the Sun and the planets called the solar system?

The system of the Sun and the planets is called the solar system because the word "solar" is derived from the Latin word "sol," which means sun. The Sun is at the center of this system, and all the planets, including Earth, orbit around it.

How many planets are therein the solar system?

There are eight planets in our solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

What is at the bottom of the solar system?

At the center of the solar system is the Sun, a star that contains about 99.8% of the solar system's mass. The Sun's gravitational force holds all the planets, moons, asteroids, and other objects in orbit around it.

How many US missions to other solar system objects have there been?

None. There are telescopes that can see other solar systems, like the Hubble telescope. However, the furthest missions have only been to the outer planets. The two voyager spacecraft, sent to Jupiter in 1977, have kept on travelling and are now the furthest objects from earth. To send something to another solar system is practically impossible, given the great distances. At the speeds we can travel, even to get to the edge of our own solar system would take thousands of years. The best we can do in terms of other solar systems is observe them from here or from the telescopes like Hubble.

Which planet is called a double planet?

None are. At one point Pluto was almost classified as one since Pluto and Charon's barycenter (the point they both rotate around) is between the two and not within Pluto. Pluto, however, is not a planet at all and so would have been a double dwarf planet had that definition been agreed on, but it was not.

In many, many years (billions) the barycenter of the Earth-Moon orbit will be outside the Earth's surface and so the Earth and Moon may be considered a double planet at that time.

What lies beyond the gas giants in the solar system?

Beyond the gas giants in our solar system (Jupiter, Saturn, Uranus, Neptune) is the region known as the Kuiper Belt, which is a vast band of small, icy objects. Past the Kuiper Belt is the Oort Cloud, a spherical region of comets that extends even farther into space.

Which planet is the second largest in the solar system?

Saturn is the second largest planet in our solar system after Jupiter.

How big is the biggest planet in the solar system?

Jupiter is the most massive planet in the Solar System - 318 times the mass of the Earth. The diameter of Jupiter is 86,881 miles (139,822 km).

Is Pluto still famous even though it's not a planet?

Yes, Pluto is still famous as it holds a special place in people's hearts and minds. Its reclassification as a "dwarf planet" has not diminished its popularity and fascination among the public and scientists.
