M.KathleenYes, in theory, moons can have moons. The region of space around a satellite where a sub-satellite can exist is called the Hill sphere. Outside the Hill sphere, a sub-satellite would be lost from its orbit about the satellite. An easy example is the Sun-Earth-Moon system..

What planet has 47 moons?
The moons of Saturn are numerous and diverse, ranging from tiny moonlets only tens of meters across to enormous Titan, which is larger than the planet Mercury.
What is the hottest planet?
It has a strong greenhouse effect, similar to the one we experience on Earth. Because of this, Venus is the hottest planet in the solar system. The surface of Venus is approximately 465°C!
Can we live on Jupiter yes or no?
The temperatures, pressures, and materials that characterize this planet are most likely too extreme and volatile for organisms to adapt to. While planet Jupiter is an unlikely place for living things to take hold, the same is not true of some of its many moons.
Why is Venus blue?
Some of the most famous images of Venus make the second planet from the Sun appear blue. However, we know that Venus actually appears mainly yellow-white to the naked eye. This blue tinting observed in some photos is as a result of the filters the cameras have used to take the image.
What color is sun in space?
But the sun itself is white. Sunlight spectrum in space as a function of wavelength.
What color is our sun really?
It is a common misconception that the Sun is yellow, or orange or even red. However, the Sun is essentially all colors mixed together, which appear to our eyes as white. This is easy to see in pictures taken from space.
Was there life Venus?
To date, no definitive evidence has been found of past or present life there. In the early 1960s, studies conducted via spacecraft demonstrated that the current Venusian environment is extreme compared to Earth’s.
Who was the first person on Earth? Adam is the name given in Genesis 1-5 to the first human. Beyond its use as the name of the first man, adam is also used in the Bible as a pronoun, individually as “a human” and in a collective sense as “mankind”.
Does Earth have 3 moons?
The simple answer is that Earth has only one moon, which we call “the moon”. It is the largest and brightest object in the night sky, and the only solar system body besides Earth that humans have visited in our space exploration efforts. The more complex answer is that the number of moons has varied over time.
Who discovered Earth?
The first person to determine the size of Earth was Eratosthenes of Cyrene, who produced a surprisingly good measurement using a simple scheme that combined geometrical calculations with physical observations.
Is moon a planet or star?
Rather than being a planet or a star, the moon is a natural satellite that orbits the Earth. The moon formed around 4.5 billion years ago due to a collision between the Earth and another planet. The debris from this collision entered into Earth’s orbit and eventually coalesced to form the moon.
How did Earth get its name?
All of the planets, except for Earth, were named after Greek and Roman gods and godesses. The name Earth is an English/German name which simply means the ground. It comes from the Old English words ‘eor(th)e’ and ‘ertha’. In German it is ‘erde’.
Where is super Earth located?
In 2019, NASA’s Transiting Exoplanet Survey Satellite (TESS) discovered a super-Earth and two mini-Neptunes orbiting a faint, cool star about 73 light-years away in the southern constellation of Pictor.
How old is the moon? The moon is a very old soul, it turns out. A new analysis of lunar rocks brought to Earth by Apollo astronauts suggests that the moon formed 4.51 billion years ago — just 60 million years after the solar system itself took shape.
Who named Sun? The word sun comes from the Old English word sunne, which itself comes from the older Proto-Germanic language’s word sunnōn. In ancient times the Sun was widely seen as a god, and the name for Sun was the name of that god. Ancient Greeks called the Sun Helios, and this word is still used to describe the Sun today.
Who named the world? The Greeks and Romans named most of the planets in the Solar System after particular gods, and we have kept those names in English. Uranus, Neptune and Pluto, all unknown in classical times, were named by the modern astronomers who discovered them, but still after Greek and Roman gods.
Does Titan have a moon?
Titan has no known moon, but it’s possible for a moon to have moons.
What moon is like Earth?
The surface of Saturn’s moon Titan looks a bit like Earth and a new study finally explains why. Saturn’s largest moon Titan features some very Earth-like landscapes: lakes and rivers, labyrinthine canyons, and soft sand dunes. However, these geological formations on Titan are made of entirely different materials.
Is Titan bigger than Earth?
Because Titan is less massive than Earth, its gravity doesn’t hold onto its gaseous envelope as tightly, so the atmosphere extends to an altitude 10 times higher than Earth’s—nearly 370 miles (600 kilometers) into space.
What is Earth’s twin planet?
Venus is often called “Earth’s twin” because they’re similar in size and structure, but Venus has extreme surface heat and a dense, toxic atmosphere.
What planet is the coldest?
The coldest planet in our solar system on record goes to Uranus which is closer to the Sun and ‘only’ about 20 times further away from the Sun than the Earth is. The lowest temperature recorded there was minus 224 degrees Celsius.
Does diamonds rain on Jupiter?
But in the dense atmospheres of planets like Jupiter and Saturn, whose massive size generates enormous amounts of gravity, crazy amounts of pressure and heat can squeeze carbon in mid-air — and make it rain diamonds.
What if you fell into Neptune?
Can humans live on Titan? Thus, Titan could potentially harbor environments with conditions suitable for life—meaning both life as we know it (in the subsurface ocean) and life as we don’t know it (in the hydrocarbon liquid on the surface).
What is Mars nickname?
Mars is known as the Red Planet.
