The online version of the well-known Stellarium simulator, an online planetarium running in your web browser, allows you to locate an asteroid more accurately. The Heavens Above also offers a list of the best asteroids to observe, showing their location among the constellations in real-time. This website contains an all-sky chart that will allow you to simultaneously see the current position of these asteroids in constellations. You can also find their upcoming opposition dates, magnitudes, and other useful information. The Sky Live informs you about the asteroids that can be observed according to your location and offers a list of planetariums and simulators that show the position of asteroids and their orbit in space.Ī lists a table of asteroids that are currently bright enough for amateur telescopes. Online sky maps provide information on asteroids’ location in real-time. Vesta, the brightest asteroid seen from Earth, reaches magnitudes between +5 and +6 when it is at its best time for observations.Įven though the Main Belt objects have higher chances to be seen than the smaller asteroids crossing the Earth’s orbit, they are still not bright enough to be observed in the same way as stars and planets.Īnother factor that comes into play here is how far the asteroid is from the Earth and the Sun. In the clear night sky, our eyes can see objects up to magnitude +6.

Therefore, negative magnitude numbers indicate very bright stars.įor example, the sun’s magnitude is estimated at -26, the Full Moon can reach -13, and Sirius, the brightest star in the night sky, has a magnitude between -1 and -2. This scale is inverse, which means that the bigger the number is, the lower the brightness. Let’s dig into the specifics.Īsteroid brightness: In Astronomy, the apparent brightness of asteroids is described with the help of the same magnitude scale used for stars, planets, and other celestial bodies. So, to be able to spot an asteroid in the night sky, it should be bright enough and at the right distance from the Earth.

Main Belt asteroids are much larger than near-Earth asteroids (NEAs) and therefore capture much more sunlight on their surface. The good news is that when it comes to Main Belt asteroids, we get more favourable observation conditions. With their small size, there is very little sunlight illuminating them and it takes more high-powered telescopes and equipment to see them. Want to see one of these near-Earth flybys? So do we! Unfortunately, it is nearly impossible for the average citizen to spot one of these space rocks. In fact, some of these asteroids pass at the nearest possible distance to our planet and luckily don’t pose any risks. Media outlets all around the world frequently report near-Earth asteroid flybys. We will also share with you some useful online resources that will help you track asteroids with more precision. You will find out how asteroid opposition impacts their brightness.

In this lesson, we will introduce you to the different factors that asteroid hunters should take into account when attempting to spot an asteroid. However, at a certain orbiting point they might pass closer to the Earth, which gives us a chance to observe them with the help of relatively simple devices. Many asteroids travel in stable orbits and therefore do not pose any threat to our planet.
