The Lyrids reach their peak on the night of April 21—22, , when you can expect to see an average of 10 meteors per hour in dark, clear skies between midnight and dawn. Rarely, the Lyrids produce surges of up to meteors per hour.
In the Northern Hemisphere, Eta Aquarids are often seen closer to the horizon. Look for the Eta Aquarids in the early pre-dawn hours of May 5, when 10—20 meteors per hour can be seen in the Northern Hemisphere and nearly double that in the Southern Hemisphere.
The Delta Aquarids get their name from the constellation Aquarius, which they appear to emanate from. A weaker shower, the Delta Aquarids typically reach their peak in late July and produce between 10 and 20 meteors per hour around this time. A truly dark sky offers the best chance at seeing the Delta Aquarids, as they tend to not be as bright as some of the other meteor showers.
This year, the Delta Aquarids mingle with the light of a bright waning gibbous Moon, which will make it more difficult to see these faint meteors.
Keep an eye out for them in the pre-dawn hours of July 28, 29, and This meteor shower is also one of the most productive of the year—expect to see up to 50 meteors per hour in a clear, dark sky.
For more viewing tips, check out our guide to the Perseid meteors! After the Draconids, a shower happens every one to two weeks until late December. This year, the Draconids reach their peak just a few days after the new Moon of October 6. The Orionids are named after one of the most recognizable constellations in the sky, Orion, from which these meteors appear to radiate. Often featuring some of brightest and fastest streaking stars, the Orionids appear in mid October and reach their peak in the hours before dawn on October For the best chance at seeing these shooting stars, venture out in the dark hours before dawn and position yourself away from the full Moon as best as you can.
My husband and I saw a meteor falling on Saturday, Nov 6, at approximately pm. Definitely a meteor, not a shooting star. Long, thick tail, and large 'starball'; and lasted much longer than a shooting star. Please post more information about meteor showers coming in Fall and Winter.
Hi, Sarah, All the major meteors are listed in the chart above. Many years ago mid 's I was driving home from my second shift job in Milford CT when suddenly there was a brilliant green streak if light seemingly at low altitude travelling south to north right above the highway.
My first thought was "WOW - fireworks". Then quickly realized it was past midnight in the middle of January. No way it was fireworks, but surely the most brilliant meteor I would ever hope to see.
Or is that referring to the hemisphere that they could best be viewed in? When a radiant point is above the horizon, more meteors may be visible the higher the radiant is in the sky, the more the meteors that can be seen. However, one should not look at the radiant, but instead select a part of the sky away from it to see the longest meteor paths. Some prefer to look straight up, to keep an eye on the most sky, or look where the sky is darkest.
Meteors can appear anywhere in the sky—just focus on one spot, and you are likely to see one or more at some time during your skywatching. Hope this helps! I live in central MA. As I watched stared out my window over the woods to beyond tonight, thinking of my kitty who escaped into the night a week ago tonight, the biggest and brightest shooting star flew right over the treetops.
Our Interactive Meteor Shower Sky Map has a meteor shower visibility conditions meter that calculates the best viewing times for your location. Just choose your preferred date and the map will provide you with the most optimal time to view the shower. Keep in mind, the visibility meter does not take into account the weather or the cloud cover at your location.
All you need is time and patience and a secluded viewing spot, away from city lights. Once you have found a safe and dark viewing spot, follow these handy tips:. These parent bodies are composed of frozen methane CH4 , ammonia NH3 , water H2O , and common gases such as carbon dioxide, CO2 , carbon dust and other trace materials.
As a comet passes near the sun in its orbit, the outer surface exposed to sunlight is vaporized and ejected in spectacular jets and streams, freeing large amounts of loosely aggregated clumps of dust and other non-volatile materials. Based upon photographic fireball studies, cometary meteoroids have extremely low densities, about 0.
These meteoroids have virtually no chance of making it to the ground unless an extremely large piece of the comet enters the atmosphere, in which case it would very likely explode at some point in its flight, due to mechanical and thermal stresses. These parent bodies are the smaller asteroids, constructed of denser and less volatile materials than the comets. Small meteoroids of this type are produced through collisions.
Stony meteorites from this source are called Chondrites, due to the rounded nodules of material found within their structure, which are called chondrules. Chondrite meteorites have two major groupings:. The first group, the Class II fireballs, are the carbon-rich Chondrites, or Carbonaceous Chondrites, which help bridge the gap between comets and asteroids. They have an average density of 3. A differentiated asteroid is one with sufficient size to cause internal temperatures high enough to melt and stratify the asteroid.
Small meteoroids of these types have been produced by what must have been spectacular collisions, breaking up even the iron core of the asteroid. These formed in the outer and crustal layers of the asteroid.
These formed a thin layer between the core and outer layers of the parent bodies. They generally consist of round, translucent green crystals of olivine imbedded in a matrix of iron. Siderites Irons ; with a 7. These are the remains of the core of a differentiated asteroid, and show signs of extremely slow cooling deg C per million years , and extremely high shock stresses, presumably from collisions.
The very rarest of meteorites are those which are thought to have originated from large differentiated bodies, such as moons and planets. Another class, the SNC shergottite-nakhlite-chassignite meteorites, are believed to have been ejected from the crust of the planet Mars. Readers of this FAQ will notice that those particles which make up the majority of the meteoroid population are those which are the least likely to make it to the ground as a meteorite.
Conversely, those particles which make up a minority of the meteoroid population are the most likely to reach the ground as a meteorite. This disparity becomes even more skewed when weathering conditions on the ground are considered. Thus, the meteors which are most often seen are not found on the surface, and the ones which are most often found are uncommon in the sky.
It took scientists many years to realize this disparity, and published texts frequently seem to conflict with one another with regard to the percentile breakdown of meteorite types. This is especially true if the author has combined old meteorite finds with fresh, observed falls. As a general rule, the smaller fainter is the meteoroid population under consideration, the more likely is a cometary origin.
As a very rough estimation, the visible meteor population is composed of about 19 cometary meteors for every 1 asteroidal meteor. This yields the following breakdown:. There are four basic fireball classes which are divided as follows:.
When only very fresh meteorite falls are considered, it becomes instantly apparent how important the density and sturdiness of the meteoroid material is to its likelihood of reaching the ground. The cometary meteoroid population disappears, and the carbonaceous chondrite population is greatly reduced.
Thus, the ordinary chondrites and non-chondritic meteorites become the primary constituents of this population:. Once they are on the ground, meteorites instantly begin to undergo mechanical and chemical weathering. Again, those meteorites which are more sturdy and dense tend to withstand these processes much better.
In this case, the iron meteorites siderites fare the best, despite their very small proportion of the overall meteoroid population:. This is an active field of study, and readers are reminded that all of the above numbers are estimates, and subject to revision as our knowledge level increases.
