What are three main objects that make up our solar system?
Our solar system consists of our star, the Sun, and everything bound to it by gravity — the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune, dwarf planets such as Pluto, dozens of moons and millions of asteroids, comets and meteoroids.
What are the 3 biggest planets?

| Rank | Planet | Diameter (Km) |
|---|---|---|
| 1 | Jupiter | 142,800 |
| 2 | Saturn | 120,660 |
| 3 | Uranus | 51,118 |

What other 3 small bodies are found in the solar system?
The small bodies in the solar system include comets, asteroids, the objects in the Kuiper Belt and the Oort cloud, small planetary satellites, Triton, Pluto, Charon, and interplanetary dust.
What is the most massive object in the solar system other than the sun?
1.) Ganymede: Jupiter’s largest moon is the largest non-planet in the Solar System. With a diameter of 5,268 km (3,271 miles), it’s 8% bigger than the planet Mercury, although it has less than half the mass of our Solar System’s innermost planet, being made of mostly ices and silicate minerals.
Where is Earth in our galaxy?
Earth is located about halfway between the center of the Milky Way and its outer edge. Light at the galaxy’s center takes 25,000 light-years to travel from Earth. (A light-year is the distance light travels in one year.)
What is the hottest planet?
Venus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night. Venus – 880°F (471°C)
Which is biggest planet on Earth?
Jupiter, being the biggest planet, gets its name from the king of the ancient Roman gods. Despite its size, Jupiter has the shortest day of any other planet; it only takes about 10 hours for a complete rotation.
What is the 8th biggest planet?
Neptune is the eighth and farthest-known Solar planet from the Sun. In the Solar System, it is the fourth-largest planet by diameter, the third-most-massive planet, and the densest giant planet. It is 17 times the mass of Earth, slightly more massive than its near-twin Uranus.
What is the 2nd biggest planet?
Saturn is the sixth planet from the Sun and the second largest planet in our solar system.
What is the smallest thing in the solar system?
In a cosmic version of the old needle-in-a-haystack finding, astronomers have spotted an object less than a mile wide that is 4.2 billion miles away, in the outer solar system. The object is part of the Kuiper Belt, a ring of icy rocks beyond Neptune.
What is the smallest celestial body?
However, Ceres (r = 470 km) is the smallest body for which detailed measurements are consistent with hydrostatic equilibrium, whereas Iapetus (r = 735 km) is the largest icy body that has been found to not be in hydrostatic equilibrium.
What is the fastest meteor?
The Leonid meteors represent the fastest known shower meteors, barreling in at 72 km/sec.
What has the most mass in our solar system?
By far most of the solar system’s mass is in the Sun itself: somewhere between 99.8 and 99.9 percent. The rest is split between the planets and their satellites, and the comets and asteroids and the dust and gas surrounding our star.
What is the biggest star?
UY Scuti
What is the largest celestial body in our solar system?
Jupiter: Our Solar System’s Largest Planet.
