Which galaxy is moving towards the Milky Way?
The Andromeda galaxy, for example, has been observed to be moving towards Earth’s Milky Way. As the universe expands, galaxies which are distant from one another appear to move away from each other since the space between them is increasing. Hubble’s Law is used to describe this expansion and its effects.
How far is the Milky Way from Earth?
Its distance from Earth is estimated at 0.081 million light years. The galaxy's official discovery was made in 1994 by Gerry Gilmore and Mike Irwin, and it was described as the Milky Way’s nearest neighbor. This galaxy has an elliptical shape, and its orbit passes over the galactic poles of the Milky Way.
What is the smallest satellite in the Milky Way?
The Ursa Major II Dwarf is known as one of the smallest of the Milky Way’s satellites. Its discovery came about from data collected by the Sloan Digital Sky Survey of 2006. The galaxy appears spheroidal, and it is 0.098 million light years from Earth. The Ursa Major II Dwarf is a faint galaxy, and its luminosity is even lesser than that of some stars such as the Milky Way’s Canopus. The galaxy is made up of old stars which are as old as 10 billion years. These stars have been theorized to be some of the first stars that formed the universe.
What is the Milky Way?
The milky way, which appears as a bright band during the night , had puzzled philosophers and astronomers in medieval times including Democritus, Aristotle, Mohani Mohammed, and Ibn Qayyim. Galileo Galilei, by the use of a telescope in 1610, discovered that the galaxy consisted of multiple stars. Since then, the Milky Way has been studied by a succession of scientists. It has a characteristic of a spiral shape and is estimated to contain approximately 100-400 billion stars. The stars which are viewed by the naked eye at night belong to this galaxy. Scientists have proposed that at the center of the galaxy exists a supermassive black hole.
What are galaxies made of?
Galaxies are collections of stars and interstellar matter which constitute the universe.

What telescope was used to see galaxies?
Observations of earlier times, when the first stars and galaxies were forming, will require Hubble’s successor, the James Webb Space Telescope (JWST). The hypothesized hierarchical growth of galaxies -- from stellar clumps to majestic spirals and ellipticals -- didn't become evident until the Hubble deep field exposures.

Who measured the distance of the Sun from the Earth?
3rd century BC — 1609. 380 Earth radii (very inaccurate, true=16000 Earth radii) Aristarchus of Samos made a measurement of the distance of the Sun from the Earth in relation to the distance of the Moon from the Earth. The distance to the Moon was described in Earth radii (20, also inaccurate).
How to determine distances to astronomical objects?
Distances to astronomical objects may be determined through parallax measurements, use of standard references such as cepheid variables or Type Ia supernovas, or redshift measurement. Spectroscopic redshift measurement is preferred, while photometric redshift measurement is also used to identify candidate high redshift sources. The symbol z represents redshift.
Which galaxy is closest to Earth?
