To ensure that the list stays stuck, just think of something along the lines of “Mercury Met Venus Every Night Until Saturn Jumped.” Essentially, this indicates that the size of the planets in order from smallest to largest is Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn, and Jupiter.
What are the gas giants in order?
The four gas giants in our solar system are Neptune, Uranus, Saturn, and Jupiter.
What is the smallest gas giant?
Neptune is the fourth largest planet in terms of diameter, making it the smallest in physical size of the gas giants. The average distance from the center of the planet to its surface is 15,299 miles (24,622 kilometers).
What is the largest gas giant?
The gassiest of all known gas giants, the unromantically named TrES-4, was discovered in 2006 orbiting a brightish star 1500 light years from Earth. Its diameter of about 1.8 times Jupiter’s makes it the largest accurately measured planet.
What are the planet sizes in order?
- Mercury – 1,516mi (2,440km) radius; about 1/3 the size of Earth.
- Venus – 3,760mi (6,052km) radius; only slightly smaller than Earth.
- Earth – 3,959mi (6,371km) radius.
- Mars – 2,106mi (3,390km) radius; about half the size of Earth.
- Jupiter – 43,441mi (69,911km) radius; 11x Earth’s size.

What are 3 characteristics of gas giants?
Unlike terrestrial planets whose composition is rocky, gas giants have a mostly gaseous composition, such as hydrogen and helium. They do have some rocky material, although this is most often found in the planet core. The four gas giants are (in order of distance from the Sun): Jupiter, Saturn, Uranus, and Neptune.
Can you land on gas giants?
A gas giant is a large planet that is not primarily composed of rock or other solid matter. … One cannot “land on” such planets in the traditional sense. There are four gas giants in our solar system: Jupiter, Saturn, Uranus, and Neptune.
Is Jupiter a failed star?
“Jupiter is called a failed star because it is made of the same elements (hydrogen and helium) as is the Sun, but it is not massive enough to have the internal pressure and temperature necessary to cause hydrogen to fuse to helium, the energy source that powers the sun and most other stars.
Can a gas giant become a star?
If a large cloud of interstellar gas came Jupiter’s way, maybe the planet could gain enough extra mass to start fusion. Fusion would be short lived if it became a brown dwarf, an object midway between star and planet. If it accreted even more mass, just enough to become a true star, it would be a dim red dwarf.
Is Pluto a gas giant?
So inconspicuous that it was not discovered until 1930, Pluto is not a gas giant planet like all the others in the outer solar system. Instead it is a small, rocky world about the size of Earth’s Moon. Recent examinations of old photographs, combined with new observations, indicate that Pluto itself has a moon.
Is the sun a gas giant?
It is, as all stars are, a hot ball of gas made up mostly of Hydrogen. The Sun is so hot that most of the gas is actually plasma, the fourth state of matter. The first state is a solid and it is the coldest state of matter. As we heat up a solid it becomes liquid.
What is the oldest thing in the universe?
GRB 090423 was also the oldest known object in the Universe, apart from the methuselah star. As the light from the burst took approximately 13 billion years to reach Earth.
What is the biggest thing on earth?
The blue whale is the largest animal living on Earth today, and it is also the largest animal in Earth’s history. It reaches 33 meters in length and 150 tons in weight.
Which planet is near to Earth today?
To find the average distance between Earth & Mars and Earth & Venus, subtract the smaller radius from the bigger one for each pair. The smaller distance gives us the closest planet. That’s Venus!
