The answer is D. “An irregular galaxy is a galaxy that does not have a distinct regular shape, unlike a spiral or an elliptical galaxy.
How would you describe an irregular galaxy?
Irregular galaxies have no particular shape . They are among the smallest galaxies and are full of gas and dust. Having a lot of gas and dust means that these galaxies have a lot of star formation going on within them. ... They are two small galaxies which orbit around our own Milky Way Galaxy.
What is the description of irregular?
Adjective. irregular, anomalous, unnatural mean not conforming to rule, law, or custom . irregular implies not conforming to a law or regulation imposed for the sake of uniformity in method, practice, or conduct.
What does a irregular galaxy look like?
Irregular galaxies have no identifiable shape or structure to them . They are often chaotic in appearance, without a bulge or any trace of spiral arms. The different shapes and orientation of galaxies are a result of their history, which may have included interactions with other galaxies.
What does an irregular galaxy most resemble?
Irregular galaxies—such as the Large and Small Magellanic Clouds that flank our Milky Way—appear misshapen and lack a distinct form , often because they are within the gravitational influence of other galaxies close by. They are full of gas and dust, which makes them great nurseries for forming new stars.
What color is a irregular galaxy?
Most representatives of this class consist of grainy, highly irregular assemblages of luminous areas. They have neither noticeable symmetry nor an obvious central nucleus, and they are generally bluer in colour than are the arms and disks of spiral galaxies.
What is a name of an irregular galaxy?
The Milky Way has two irregular “satellite” galaxies, called the Large and Small Magellanic Clouds .

What are the 4 types of galaxy?
Galaxies 101
The smallest of galaxies contain a “mere” few hundred million stars while the largest galaxies contain up to one hundred trillion stars! Scientists have been able to segment galaxies into 4 main types: spiral, elliptical, peculiar, and irregular .
What is the age of an irregular galaxy?
The very bright stars in the picture, those with spikes around them, are stars in the foreground belonging to the Milky Way. The main body of SagDig is rich in gas, and contains many regions of active star formation. Indeed, the average age of the stars in the galaxy is a relatively young 4 to 8 billion years .
Which of the following best describes an irregular galaxy?
An irregular galaxy is a galaxy that does not have a distinct regular shape , unlike a spiral or an elliptical galaxy. Irregular galaxies do not fall into any of the regular classes of the Hubble sequence, and they are often chaotic in appearance, with neither a nuclear bulge nor any trace of spiral arm structure.
How do stars move in an irregular galaxy?
The stars then move on elliptical orbits around the center, but are perturbed by local irregularities . In spirals and elliptical, the potential is rather symmetric, whereas in irregulars it is quite... irregular.
How is an irregular galaxy formed?
Irregular galaxies often form when one galaxy collides with another . Here, a smaller galaxy passed through the middle of a large spiral galaxy, forming this irregular Cartwheel Galaxy.
What is the closest irregular galaxy?
The closest galaxy to the Milky Way happens to be an irregular galaxy called the Canis Major Dwarf . With just one billion stars, it appears to be a small galaxy in the process of being consumed by our own galaxy.
