Comet Nishimura, which was only discovered in August, has survived its closest approach to the sun and will brighten over the next week. But is it still visible from Earth?
Comets are remnants from the early days of the solar system, billions of years ago. Primarily made of ice and dust, these "dirty snowballs" orbit the sun and in habit the Oort cloud, an area in the outskirts of the solar system beyond Pluto. As comets approach the inner solar system, solar wind from the sun can sweep dust back into a long tail. When these comets are close enough to Earth, they can appear as dazzling objects in the night sky. Space probes from Earth have visited several comets to learn more about their composition.

Comet Nishimura has surprised NASA by photobombing its STEREO spacecraft, revealing it seems to have held together after its brush with the sun on Sept. 17.
There's a slight chance Comet Nishimura might brighten unexpectedly. Astronomer Jonti Horner explains what to expect.
The newfound Comet P1 (Nishimura) passes its closest point to Earth on Tuesday (Sept. 12). Here's how to see it this week before it's gone for 400 years.
Astrophotographers worldwide have been snapping incredible photos of Comet Nishimura as it makes its way through the solar system.
While social media has been abuzz with talk of new Comet Nishimura being visible to the naked eye in September, experts aren't so sure.
The exploding comet, known as 12P/Pons–Brooks, is currently approaching its closest point to Earth during its 71-year orbit through the solar system.
Comet C/2022 E3 made a close pass by our planet in January, and a new video captures its incredible journey in 4K resolution.
The velocity of interstellar objects passing through our solar system, like 'Oumuamua, can be correlated to their chemistry and the type of star they came from.
A comet discovered just months ago will make for an easy-to-spot, if somewhat dim, target for summer skywatchers eager to see a snowball streak through the solar system.
Forty years ago this month, there came a show stopping celestial sight — literally a bolt out of the blue — as a new comet was discovered close to Earth.
The James Webb Space Telescope has imaged a rare main asteroid belt comet, discovering water around the object that could help reveal how Earth became a wet planet teeming with life.
Since its arrival in the solar system in 2017, interstellar object 'Oumuamua has puzzled scientists. Two American astronomers now think they have solved one of the space rock's biggest mysteries.
A comet recently discovered zooming through our solar system has the potential to be quite bright when it arrives late in 2024, but comets have let us down before.
For the next few weeks in March, the sky to the west is illuminated by a pyramid of ethereal glow after twilight known as the zodiacal light.
The newly discovered comet C/2023 A3 is making a close approach around the sun for the first time in 80,000 years, and might be as bright as a star in fall 2024.
A Japanese cubesat launched aboard NASA's Artemis 1 moon mission took a video of Comet C/2022 E3 (ZTF) earlier this month, about two weeks after the ice ball's closest approach to Earth.
The comet C/2022 A2 (Pan-STARRS) will pass close by the sun on Sunday (Feb. 19), making its first and likely final approach to our star.
The comet C/2022 A2 (Pan-STARRS) will reach perihelion, or the closest point to the sun in its orbit, on Saturday, Feb. 18. The comet will be visible from Earth at dawn and dusk.
Green comet C/2022 E3 (ZTF) has been predicted to have a period of 50,000 years, but there’s a chance it’s racing out of the solar system.
