Which astronomical object is our solar system?
Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids.

How many astronomical objects are there?
Nearly 700 million astronomical objects have been carefully catalogued and made public as part of a major international collaboration involving researchers from The Australian National University (ANU).
Which is an astronomical object orbiting the Earth or any other planet?
satellite, natural object (moon) or spacecraft (artificial satellite) orbiting a larger astronomical body. Most known natural satellites orbit planets; the Earth’s Moon is the most obvious example. All the planets in the solar system except Mercury and Venus have natural satellites.
How many stars are there around the sun?
Today, high-powered telescopes offer even more granular data on our cosmic neighborhood. The infographic above, from Alan’s Factory Outlet, categorizes the 44 closest stars to Earth, examining the size, luminosity, constellations, systems, and potential planets of each star.
What are space objects?
Space object can be described as any object launched into orbit from Earth, the Moon or other celestial bodies to travel to, in or through outer space, all artificial objects likely to find or evolve in outer space without the bearing strength of the air.
What are things in the galaxy?
They contain stars, planets, moons, comets, asteroids, nebulae, dust, neutron stars, and black holes. Many probably even contain large amounts of unseen dark matter. Since most of the space between galaxies is thought to be empty, a galaxy is essentially an oasis in space.
How are astronomical objects named?
When reported to the IAU Central Bureau for Astronomical Telegrams, the object is assigned a provisional name, consisting on the letter S followed by the year of discovery and a number indicating the order of discovery within that year. When the satellite is confirmed, the discoverer suggests a final name.
What is our galaxy name?
The Milky Way
The Milky Way gets its name from a Greek myth about the goddess Hera who sprayed milk across the sky. In other parts of the world, our galaxy goes by other names.
How do astronomers take pictures of Faraway nebulae?
Astronomers use very powerful telescopes to take pictures of faraway nebulae. Space telescopes such as NASA’s Spitzer Space Telescope and Hubble Space Telescope have captured many images of faraway nebulae.
What is the best telescope to see nebulae?
The scope features a Maksutov-Cassegrain Optical Design with a 127mm (5”) aperture. The large-high-quality lens gathers enough light to give stunning views of the solar system and deep space objects. We were able to see Saturn’s rings, Jupiter’s cloud bands, and the craters on the Moon. This is a great telescope to see nebula.
What is a nebula in space?
A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova. Other nebulae are regions where new stars are beginning to form. YouTube. NASA Space Place.
What are the best telescopes for observing the universe?
The nebula telescope includes an accessory tray to store your accessories while observing. To add to the excitement, it comes with a Bonus Autostar Suite Astronomy planetarium DVD, which offers over 10,000 celestial objects. 3. Orion SpaceProbe 130ST EQ Reflector Telescope
