Do we have another interstellar visitor?

In summary, a new comet-like object has been discovered by amateur astronomer Gennady Borisov, using his self-made telescope. This object, larger than the Oumaouma object that was previously identified as coming from interstellar space, is still on its way towards the sun, allowing for more time for observation. As technology improves, we can expect to find more objects from outside our solar system.

TL;DR Summary
Incoming object identified with hyperbolic trajectory.
In 2017 the intriguing Oumaouma object was determined to have reached us from interstellar space. Now another object, this time larger and likely a comet, has been identified, apparently from outwith the system.

More here on the BBC site and The Minor Planet centre.

Unlike its predecessor, this one is still on its way sunward so there should be lots of time for observation.

This is kind of amazing:

Here's an amazing fact: The discoverer, Gennady Borisov, is an amateur astronomer who works as an engineer at the Sternberg Astronomical Institute. He makes his own telescopes to hunt for comets and has discovered seven of them along with several NEOs. He recently completed a new 0.65-meter telescope, the instrument he used to discover the new object.

1. What is an interstellar visitor?

An interstellar visitor is an object that comes from outside of our solar system and passes through our solar system. This could be a comet, asteroid, or other celestial body.

2. How often do interstellar visitors come to our solar system?

It is difficult to determine how often interstellar visitors come to our solar system, as they are not always detected. However, recent estimates suggest that one interstellar visitor may pass through our solar system every few years.

3. How do we detect interstellar visitors?

Interstellar visitors are typically detected through telescopes and other astronomical instruments. They may also be detected through their effects on other objects in our solar system, such as gravitational disturbances.

4. What was the first interstellar visitor that we detected?

The first interstellar visitor that we detected was an object called 'Oumuamua, which was discovered in 2017. It was classified as an interstellar comet and passed through our solar system at a high speed.

5. Do interstellar visitors pose a threat to Earth?

The likelihood of an interstellar visitor posing a threat to Earth is very low, as most objects that pass through our solar system do not come close enough to Earth to cause any harm. However, it is important for scientists to continue monitoring and studying these objects to better understand their potential impact on our solar system.
