NASA Animation Sizes Up the Universe''s Biggest Black Holes
Its shadow diameter spans about half that of Mercury''s orbit in our solar system. The animation shows two monster black holes in the galaxy known as NGC 7727. Located about 1,600 light-years apart, one weighs 6 million solar masses and the other more than 150 million Suns. Astronomers say the pair will merge within the next 250 million years.
Moons of Our Solar System
How Many Moons Are in Our Solar System? Naturally-formed bodies that orbit planets are called moons, or planetary satellites. The best-known planetary satellite is, of course, Earth''s Moon. Since it was named before we learned about other planetary satellites, it is called simply "Moon." According to the NASA/JPL Solar System Dynamics team, the current tally []

The following objects have a nominal mean radius of 400 km or greater. It was once expected that any icy body larger than approximately 200 km in radius was likely to be in hydrostatic equilibrium (HE).

A trip at light speed to the very edge of our solar system – the farthest reaches of the Oort Cloud, a collection of dormant comets way, way out there – would take about 1.87 years. Keep going to Proxima Centauri, our nearest neighboring star, and plan on arriving in 4.25
6 FAQs about [Is the galaxy bigger than the solar system]
Is a galaxy bigger than a star?
It is significantly bigger than a star. A galaxy, such as our Milky Way Galaxy, is a collection of solar systems orbiting around a central core. Most galaxies have a supermassive black hole at their centres. Galaxies also form clusters which are large scale structures. The universe is everything. It contains billions of galaxies.
What is the difference between galaxies and solar systems?
Scale is the main difference between solar systems, galaxies, and the Universe. Solar systems are based around a single star. Galaxies are made of millions-trillions of stars, including those with planets going around them. The Universe contains all two trillion galaxies and their countless solar systems.
Are galaxies bigger than the Milky Way?
Galaxies come in many sizes. The Milky Way is big, but some galaxies, like our Andromeda Galaxy neighbor, are much larger. The universe is all of the galaxies – billions of them! NASA’s telescopes allow us to study galaxies beyond our own in exquisite detail, and to explore the most distant reaches of the observable universe.
Is a Solar System bigger than a star?
A solar system is a star and all of its planets, asteroids, comets and other bodies. It is significantly bigger than a star. A galaxy, such as our Milky Way Galaxy, is a collection of solar systems orbiting around a central core. Most galaxies have a supermassive black hole at their centres.
Is a Solar System smaller than a Galaxy?
No, a solar system is not bigger than a galaxy. In fact, a galaxy is tremendously larger. This size difference is due to the differing nature of these two cosmic entities.
Is a galaxy a solar system?
A galaxy is a system of solar systems and other stars. Galaxies, like solar systems, are held together by gravity. In galaxies, the solar systems are separated by vast sections of mostly empty space. The galaxy that contains the Earth and its solar system is called the Milky Way.
