What are the 8 planets and their characteristics?
The four closest to the sun — Mercury, Venus, Earth and Mars — are the terrestrial planets. They have rocky surfaces enclosed by relatively shallow atmospheres. The gas and ice giants — Jupiter, Saturn, Uranus and Neptune — are outliers.
What are the four major features of the solar system?
Four Major Characteristics of the Solar System
- smaller size and mass.
- higher density (rocks and metal)
- solid surface.
- few moons and rings.
- closer to the Sun.
What are the 3 characteristics of planets?
It says a planet must do three things: It must orbit a star (in our cosmic neighborhood, the Sun). It must be big enough to have enough gravity to force it into a spherical shape. It must be big enough that its gravity cleared away any other objects of a similar size near its orbit around the Sun.
What are the main characteristics of the planets?
The characteristics of a planet are that it (a) is in orbit around the sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium [nearly round] shape, and (c) has cleared the neighborhood around its orbit.
What are the 15 planets?
Planets in Our Solar System
- Mercury. Mercury—the smallest planet in our solar system and closest to the Sun—is only slightly larger than Earth’s Moon.
- Venus. Venus spins slowly in the opposite direction from most planets.
- Earth.
- Mars.
- Jupiter.
- Saturn.
- Uranus.
- Neptune.
What are the two features of planets?
1]Surfaces. Many forces shape the solid surfaces of planets and moons. 2]Ring systems. All of the gas giant planets—Jupiter, Saturn, Uranus, and Neptune—have rings.
What do all planets have in common?
1 Answer. Patrick H. Besides all of them being planets, all follow an elliptical orbit, all are spherical, and all are made of iron and nickel to some degree.
What are the 8 planets called?
The eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Mercury is closest to the Sun.
Are there 8 or 9 planets?
The order of the planets in the solar system, starting nearest the sun and working outward is the following: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then the possible Planet Nine. If you insist on including Pluto, it would come after Neptune on the list.

Is there a 10th planet?
The planet, which hasn’t been officially named yet, was found by Brown and colleagues using the Samuel Oschin Telescope at Palomar Observatory near San Diego. It is currently about 97 times farther from the sun than Earth, or 97 Astronomical Units (AU).
Who is called tenth planet?
Because Eris was initially thought to be larger than Pluto, it was described as the “tenth planet” by NASA and in media reports of its discovery.
Who found the 10 planet?
The 10th planet was discovered using the Samuel Oschin Telescope at Palomar Observatory near San Diego, Calif. The discovery was announced today by planetary scientist Dr. Mike Brown of the California Institute of Technology in Pasadena, Calif., whose research is partly funded by NASA.
What is the 13th planet?
Naming of Eris:
As a result, the discovery team proposed Eris on September 6th, 2006, and by the 13th, the name was accepted as the official name by the IAU. Brown favored this name for two reasons.
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)
What is the new 9th planet called?
Planet Nine is a hypothetical planet in the outer region of the Solar System. Its gravitational effects could explain the unusual clustering of orbits for a group of extreme trans-Neptunian objects (ETNOs), bodies beyond Neptune that orbit the Sun at distances averaging more than 250 times that of the Earth.
What planet is closest to the Earth?
Essentially because Mercury is closest to the Sun, when taking an average over time, Mercury is the closest planet to the Earth, and—in that measure—it is the closest planet to each of the other planets in the Solar System.
