When a comet's orbit brings it close to the Sun, it heats up and spews dust and gases into a giant glowing head larger than most planets. The dust and gases form a tail that stretches away from …
These phenomena are due to the effects of solar radiation and the outstreaming solar wind plasma acting upon the nucleus of the comet. Comet nuclei range from a few hundred meters to tens of kilometers …

However, as a comet comes closer to the Sun, the Sun’s heat and radiation vaporize its ice and dust. These vaporized gasses collect dust and stream from the center of the comet, just like a tail.
Comet C/2025 R3 is already drawing attention—and offers a rare chance to understand what separates an ordinary comet from a truly “great” one.
Comet C/2025 R3 is putting on its final show as it passes close to the Sun before leaving the solar system forever.

When a comet's orbit brings it close to the Sun, it heats up and spews dust and gases into a giant glowing head larger than most planets. The dust and gases form a tail that stretches away from the Sun for millions of miles.
These phenomena are due to the effects of solar radiation and the outstreaming solar wind plasma acting upon the nucleus of the comet. Comet nuclei range from a few hundred meters to tens of kilometers across and are composed of loose collections of ice, dust, and small rocky particles.
Comet, a small body orbiting the Sun with a substantial fraction of its composition made up of volatile ices. Comets are among the most-spectacular objects in the sky, with their bright glowing comae and their long tails.
When a comet is in the inner Solar System, the Sun warms it up, causing the comet's ice to vaporize and release dust and gas particles. The solar wind blows those particles off the comet, and we see the dust and ion tails.
C/2026 A1 ( MAPS ) Kreutz sungrazer comet discovered furthest from Sun in history. It approached to Sun down to 0.005 a.u. on Apr. 4. It brightened up to 7.7 mag until it set down under the horizon before the perihelion passage (Mar. 29, Chris Wyatt). It brightened up to about -1 mag in the SOHO spacecraft images (Apr. 4, Robert Pickard).

Comet C/2025 R3 (PanSTARRS) is approaching Earth and should be visible to the naked eye between April 13 and April 15, appearing low on the eastern horizon just before sunrise.
According to NASA ’s April skywatching guidance, Comet C/2025 R3 will reach its closest approach to Earth on April 27, when it comes within about 44 million miles of the planet.
