Is there other planets like Earth in other galaxies?

Other galaxies could be full of sibling Earths: In fact, evidence suggests there may be as many as one Earth-like planet for every five Sun-like stars in the Milky Way alone. Earth is our home, which makes it special in its own right.Aug 23, 2021

The sun, the planets, dwarf planets (Pluto), natural satellites (like the moon), asteroids, comets, meteoroids, meteors, and meteorites. Objects NOT found in our solar system: Galaxies, other stars, constellations, the universe, black holes, supernovas and nebulae.

Topics covered includes: Motion, Forces and Newton's Laws, Work and Energy, Rotational Motion, Gravity, Fluids, Heat, Electricity and Magnetism, Light, Special Relativity, Quantum Theory, Earth and other Planets, Stars, Galaxies, and the Universe.

Natural Satellite

The term is used for moons which go around planets, and it is also used for small galaxies which orbit larger galaxies. Bodies which orbit planets are called moons. They vary in size. The Earth has only one moon.

Natural Satellite

Gravity is a force of attraction that exists between any two objects. There is a force of gravity between the sun and the Earth, between the Earth and us, and even between two marbles. Projectiles, satellites, planets, galaxies, and clusters of galaxies are all influenced by Gravity.

The only thing expanding is space itself. Space is expanding from the Big Bang and the acceleration of dark energy. But the objects embedded in space, like planets, stars, and galaxies stay exactly the same size. As space expands, it carries galaxies away from each other.

Earth is one of six planets, just like any other planet. "By making the Earth just another planet, Nicholas Copernicus, in 1543, hurled an imiplicit challenge to the concept of incorruptibility.

We Live In A Cosmic Void, Another Study Confirms

Earth and its parent galaxy are living in a cosmic desert — a region of space largely devoid of other galaxies, stars and planets, according to a new study. The findings confirm the results of a previous study based on observations taken in 2013.

Geoscientist, a person studying Earth or other planets using Earth science. Geologist, a scientist who studies the solid, liquid, and gaseous matter that constitutes the Earth and other terrestrial planets. Geochemist (see Geochemistry)

Earth sciences is the study of the Earth. Some Earth scientists investigate how the Earth and other planets formed, others explore energy and mineral resources, provide advice for safe construction, or study natural processes like volcanoes.

For example, if you're wanting to view faint deep-sky objects like nebulas and galaxies then you'll want a reflector telescope. On the other hand, a refractor telescope is better suited for views within our own galaxy such as the moon and other planets.

Planets Rock? Planets ?

Earth and the other three inner planets of our solar system (Mercury, Venus and Mars) are made of rock, containing common minerals like feldspars and metals like magnesium and aluminum. So is Pluto. The other planets are not solid. Jupiter, for instance, is made up mostly of trapped helium, hydrogen, and water.
